Wikimedia Commons, which relies on freely licensed content, opposes practices that undermine the spirit of open use and sharing. However, the point at which copyright enforcement turns into copyleft trolling is not always clear. Common themes of copyleft trolling include refusing to allow violators to fix their errors rather than pay a fee, indifference to the identity or size of the violator, using an overly complicated attribution line to increase the likelihood of mistakes, demanding money for both minor and major violations, and using old Creative Commons licenses that make it easier to make a business out of enforcement. Working with companies such as Pixsy, which make it easy to pursue money for alleged infringements, may lead even well-meaning contributors to engage in copyleft trolling. Wikimedia Commons typically takes a case-by-case approach to dealing with these issues, and in extreme cases Commons has deleted or forcibly watermarked all of a user's files. This guideline explains copyleft trolling and associated concepts, provides some tips for differentiating it from other forms of copyright enforcement, and outlines the ways the Commons community has intervened in the past. </p> <div id="toc" class="toc" role="navigation" aria-labelledby="mw-toc-heading"><input type="checkbox" role="button" id="toctogglecheckbox" class="toctogglecheckbox" style="display:none" /><div class="toctitle" lang="en" dir="ltr"><h2 id="mw-toc-heading">Contents</h2><span class="toctogglespan"><label class="toctogglelabel" for="toctogglecheckbox"></label></span></div> <ul> <li class="toclevel-1 tocsection-1"><a href="#What_is_copyleft_trolling"><span class="tocnumber">1</span> <span class="toctext">What is copyleft trolling</span></a></li> <li class="toclevel-1 tocsection-2"><a href="#Copyright_enforcement_vs._copyleft_trolling"><span class="tocnumber">2</span> <span class="toctext">Copyright enforcement vs. copyleft trolling</span></a></li> <li class="toclevel-1 tocsection-3"><a href="#License_considerations"><span class="tocnumber">3</span> <span class="toctext">License considerations</span></a></li> <li class="toclevel-1 tocsection-4"><a href="#How_Pixsy_works"><span class="tocnumber">4</span> <span class="toctext">How Pixsy works</span></a></li> <li class="toclevel-1 tocsection-5"><a href="#How_Commons_handles_copyleft_trolls"><span class="tocnumber">5</span> <span class="toctext">How Commons handles copyleft trolls</span></a> <ul> <li class="toclevel-2 tocsection-6"><a href="#Verification"><span class="tocnumber">5.1</span> <span class="toctext">Verification</span></a></li> <li class="toclevel-2 tocsection-7"><a href="#Deletion"><span class="tocnumber">5.2</span> <span class="toctext">Deletion</span></a></li> <li class="toclevel-2 tocsection-8"><a href="#Forced_watermarking"><span class="tocnumber">5.3</span> <span class="toctext">Forced watermarking</span></a></li> <li class="toclevel-2 tocsection-9"><a href="#No_standard_practice"><span class="tocnumber">5.4</span> <span class="toctext">No standard practice</span></a></li> </ul> </li> <li class="toclevel-1 tocsection-10"><a href="#Additional_steps_Commons_could_take"><span class="tocnumber">6</span> <span class="toctext">Additional steps Commons could take</span></a> <ul> <li class="toclevel-2 tocsection-11"><a href="#Deprecate_older_Creative_Commons_licenses"><span class="tocnumber">6.1</span> <span class="toctext">Deprecate older Creative Commons licenses</span></a></li> <li class="toclevel-2 tocsection-12"><a href="#Improve_visibility_of_license_terms"><span class="tocnumber">6.2</span> <span class="toctext">Improve visibility of license terms</span></a></li> <li class="toclevel-2 tocsection-13"><a href="#Follow_the_Flickr_model"><span class="tocnumber">6.3</span> <span class="toctext">Follow the Flickr model</span></a> <ul> <li class="toclevel-3 tocsection-14"><a href="#Implications"><span class="tocnumber">6.3.1</span> <span class="toctext">Implications</span></a></li> </ul> </li> </ul> </li> <li class="toclevel-1 tocsection-15"><a href="#Victim_of_copyleft_trolling?"><span class="tocnumber">7</span> <span class="toctext">Victim of copyleft trolling?</span></a> <ul> <li class="toclevel-2 tocsection-16"><a href="#Resources"><span class="tocnumber">7.1</span> <span class="toctext">Resources</span></a></li> </ul> </li> <li class="toclevel-1 tocsection-17"><a href="#See_also"><span class="tocnumber">8</span> <span class="toctext">See also</span></a></li> <li class="toclevel-1 tocsection-18"><a href="#Further_reading"><span class="tocnumber">9</span> <span class="toctext">Further reading</span></a></li> </ul> </div> <div class="mw-heading mw-heading2 ext-discussiontools-init-section"><h2 id="What_is_copyleft_trolling" data-mw-thread-id="h-What_is_copyleft_trolling"><span data-mw-comment-start="" id="h-What_is_copyleft_trolling"></span>What is copyleft trolling<span data-mw-comment-end="h-What_is_copyleft_trolling"></span></h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Commons:Copyleft_trolling&action=edit&section=1" title="Edit section: What is copyleft trolling"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span><!--__DTELLIPSISBUTTON__{"threadItem":{"headingLevel":2,"name":"h-","type":"heading","level":0,"id":"h-What_is_copyleft_trolling","replies":[]}}--></div> <p>When a copyright owner uses a Creative Commons license, they are communicating a desire for others to use their work. Copyleft trolls employ a Creative Commons license to exploit the "you can use this!" signal to take legal action against those who commit minor violations of licensing requirements in reusing the troll's copyrighted work. Copyleft trolls will often target independent or small-time reusers who cannot afford to mount a legal defense, even if the offense is trivial and even if the violation is rapidly corrected. The intent is not to actually go to court, but to intimidate the other party into a cash settlement. </p><p>The term "copyleft troll" comes from <a href="https://en.wikipedia.org/wiki/copyright_troll" class="extiw" title="w:copyright troll">"copyright troll"</a>, companies who used automated processes to find copyrighted works online and issue legal threats and demands at scale. As an example, the website <i>Ars Technica</i> followed the firm <a rel="nofollow" class="external text" href="https://arstechnica.com/series/whos-behind-prenda-law/">Prenda</a>'s copy<i>right</i> trolling in detail. The best-known company associated with copy<i>left</i> trolling is Pixsy, which similarly uses automated systems to search for violations and provides an interface that simplifies demanding money from people who misuse freely licensed images. </p><p>Freely licensed content is a cornerstone of Wikimedia projects. Wikimedia Commons wants people to use our content in a variety of ways, and to be confident that they will not be targeted for good faith mistakes. A business model based on suing independent media users for trivial license violations is not in line with the values of Wikimedia Commons. For example, if a personal blogger, social media user, or local charity finds an image on Wikipedia and uses it, crediting the author and citing Wikimedia Commons, but fails to link to the license, that is technically a violation of standard Creative Commons Attribution licenses. It is not, however, the sort of violation we would expect Wikimedia contributors to take legal action over, especially if the reuser offers to fix the error. Creative Commons itself published <a rel="nofollow" class="external text" href="https://creativecommons.org/2022/02/08/copyleft-trolls/">a blog post about copyleft trolling</a> in 2022, saying "Put simply, 'license-enforcement-as-business model' is a perversion of the founding ideals of Creative Commons. We condemn this behavior." </p> <div class="mw-heading mw-heading2 ext-discussiontools-init-section"><h2 id="Copyright_enforcement_vs._copyleft_trolling" data-mw-thread-id="h-Copyright_enforcement_vs._copyleft_trolling"><span data-mw-comment-start="" id="h-Copyright_enforcement_vs._copyleft_trolling"></span>Copyright enforcement vs. copyleft trolling<span data-mw-comment-end="h-Copyright_enforcement_vs._copyleft_trolling"></span></h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Commons:Copyleft_trolling&action=edit&section=2" title="Edit section: Copyright enforcement vs. copyleft trolling"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span><!--__DTELLIPSISBUTTON__{"threadItem":{"headingLevel":2,"name":"h-","type":"heading","level":0,"id":"h-Copyright_enforcement_vs._copyleft_trolling","replies":[]}}--></div> <p>Wikimedia Commons is not solely a repository of public domain content free from all licensing restrictions. We host media with <a href="/wiki/Commons:Licensing" title="Commons:Licensing">a wide range of free licenses</a> and therefore much of our content has legal restrictions on use. In other words, media owners who upload here and use a license like CC-BY have the ability to take action against violators. If they didn't, the license would be functionally public domain. At what point enforcement begins to look like copyleft trolling will require judgment on a case-by-case basis, but will typically involve some combination of the following: </p> <ul><li>Working with a company that uses automated processes to find violations and issue letters asking for money.</li> <li>Does not differentiate between independent/small-time reusers and large corporations, except perhaps in the amount of money requested.</li> <li>Does not differentiate between audience sizes in uses, treating a personal blog with a handful of readers as equivalent to a popular national television program.</li> <li>Does not differentiate between types of offenses, such that failing to attribute altogether is treated as equivalent to forgetting a link to the license.</li> <li>Does not provide an opportunity to correct the error. May reduce the amount requested for a correction, but will demand money nonetheless.</li> <li>Once the error is corrected, license is not restored and additional moneys may be demanded (see <a href="#License_considerations">license considerations</a>).</li></ul> <p>According to Creative Commons, there are <a rel="nofollow" class="external text" href="https://creativecommons.org/license-enforcement/enforcement-principles/">three principles</a> which should guide enforcement of such licenses: "the primary goal of license enforcement should be getting reusers to comply with the license", "legal action should be taken sparingly", and "enforcement may involve monetary compensation, but should not be a business model". Importantly, however, these principles communicate the values of the organization behind the licenses but do not themselves have legal bearing; only the licenses themselves do. </p><p>Working with firms like Pixsy increases the likelihood that enforcement will veer closer to copyleft trolling. Unfortunately there is not much middle-ground between copyright owners searching and handling violations themselves and contracting with unethical firms. From the perspective of media reusers, there is little difference between well-meaning contributors who follow such a company's lead and bad faith contributors who upload with the intention of copyleft trolling. </p> <div class="mw-heading mw-heading2 ext-discussiontools-init-section"><h2 id="License_considerations" data-mw-thread-id="h-License_considerations"><span data-mw-comment-start="" id="h-License_considerations"></span>License considerations<span data-mw-comment-end="h-License_considerations"></span></h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Commons:Copyleft_trolling&action=edit&section=3" title="Edit section: License considerations"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span><!--__DTELLIPSISBUTTON__{"threadItem":{"headingLevel":2,"name":"h-","type":"heading","level":0,"id":"h-License_considerations","replies":[]}}--></div> <p>Creative Commons licenses are periodically updated. One of the major differences from 3.0 to 4.0 is the addition of a remedy clause. In older versions of the license, once you violate the license the agreement is void -- you are no longer allowed to use the image, even if you fix the attribution later. This provides additional opportunities to copyleft trolls to seek damages at multiple points over time, even after the reuser has paid an initial sum. Version 4.0 doesn't prohibit copyright owners from seeking money from people for violations of the license, but does <i>restore</i> the license once the mistake has been corrected. In other words, upgrading licenses to version 4.0 does not prevent copyleft trolling but does make it a little less lucrative. It also prevents users from seeking damages with Pixsy, which will not pursue cases involving CC 4.0 licenses. </p> <div class="mw-heading mw-heading2 ext-discussiontools-init-section"><h2 id="How_Pixsy_works" data-mw-thread-id="h-How_Pixsy_works"><span data-mw-comment-start="" id="h-How_Pixsy_works"></span>How Pixsy works<span data-mw-comment-end="h-How_Pixsy_works"></span></h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Commons:Copyleft_trolling&action=edit&section=4" title="Edit section: How Pixsy works"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span><!--__DTELLIPSISBUTTON__{"threadItem":{"headingLevel":2,"name":"h-","type":"heading","level":0,"id":"h-How_Pixsy_works","replies":[]}}--></div> <p>Pixsy is an "image theft protection" service. Its clients provide photos which Pixsy then uses to search for uses across the internet, organizing those violations into a number of categories (country the site is hosted in, number of images used, whether the image is still online or not, commercial uses, etc.). The copyright owners then browse the uses to look for violations. Like any reverse image search, there are false positives and the burden is on the user to differentiate the images. As the service was intended primarily for copyright enforcement, and not necessarily copyleft enforcement, users are expected to verify that the terms of their free license were violated. Upon finding a violation and deciding to take action, the user has two options: pursue damages or issue a takedown notice. The latter is disincentivized -- users get a limited number of notices as part of their membership and then must pay a fee to use the feature. All it takes to pursue damages is clicking "pursue", at which point Pixsy takes over. If/when the media reuser pays a fee, Pixsy and the copyright owner split it. </p> <ul><li>Pixsy says it only pursues commercial users, and does not seek damages from uses on personal blogs, personal social media sites, etc., although these users can be issued takedown requests.</li> <li>Pixsy does not issue demand letters without the copyright owner initiating the process.</li> <li>Once Pixsy takes over the case, the role of the copyright owner is minimal.</li> <li>Pixsy does not accept images licensed with Creative Commons version 4.0 licenses.</li></ul> <div class="mw-heading mw-heading2 ext-discussiontools-init-section"><h2 id="How_Commons_handles_copyleft_trolls" data-mw-thread-id="h-How_Commons_handles_copyleft_trolls"><span data-mw-comment-start="" id="h-How_Commons_handles_copyleft_trolls"></span>How Commons handles copyleft trolls<span data-mw-comment-end="h-How_Commons_handles_copyleft_trolls"></span></h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Commons:Copyleft_trolling&action=edit&section=5" title="Edit section: How Commons handles copyleft trolls"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span><!--__DTELLIPSISBUTTON__{"threadItem":{"headingLevel":2,"name":"h-","type":"heading","level":0,"id":"h-How_Commons_handles_copyleft_trolls","replies":["h-Verification-How_Commons_handles_copyleft_trolls","h-Deletion-How_Commons_handles_copyleft_trolls","h-Forced_watermarking-How_Commons_handles_copyleft_trolls","h-No_standard_practice-How_Commons_handles_copyleft_trolls"]}}--></div> <p>Commons does not have any bright-line rule which attempts to restrict the ways copyright owners can enforce their licenses and does not attempt to prohibit users from working with companies like Pixsy.

Before seeking such remedies, it's important to verify the claims of copyleft trolling. For example, if we learn that an individual reuser received a letter from a law firm demanding money, take steps to verify the claims: was there a license violation, was there any attempt to correct it, does the law firm represent the copyright owner, have there been other complaints about the same user in the past? Some of these questions will not be answerable; the important thing is due diligence to try to substantiate the claims.

Per the section on licenses above, this would not prevent copyleft trolling but could limit some of the harms in some cases and would preclude the involvement of Pixsy. As much of our media are not uploaded by the copyright owners and as a large amount of media are owned by users no longer active on Commons, this would be difficult to enforce unless it applied only to new uploads of media created after the introduction of v4.0. </p> <div class="mw-heading mw-heading3"><h3 id="Improve_visibility_of_license_terms" data-mw-thread-id="h-Improve_visibility_of_license_terms-Additional_steps_Commons_could_take"><span data-mw-comment-start="" id="h-Improve_visibility_of_license_terms-Additional_steps_Commons_could_take"></span>Improve visibility of license terms<span data-mw-comment-end="h-Improve_visibility_of_license_terms-Additional_steps_Commons_could_take"></span></h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Commons:Copyleft_trolling&action=edit&section=12" title="Edit section: Improve visibility of license terms"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>It is easy for someone to click an image on Wikipedia and save the file from the Commons page without scrolling down to understand the licensing requirements.

In one case, a professional photographer explained that his photos are used widely by major media organizations, and that while he shares some photos on Commons for anyone to use with attribution, he charges a fee for unattributed uses such as for use in advertisements. But there is little, if any, opposition among the community for enforcing licenses when it comes to major corporations using unattributed images in advertisements. It becomes copyleft trolling when enforcement becomes indiscriminate, making a business model out of extracting money from any minor violation, regardless of whether it's fixed, and not just companies who failed to attribute altogether. </p> <div class="mw-heading mw-heading2 ext-discussiontools-init-section"><h2 id="Victim_of_copyleft_trolling?" data-mw-thread-id="h-Victim_of_copyleft_trolling?"><span id="Victim_of_copyleft_trolling.3F"></span><span data-mw-comment-start="" id="h-Victim_of_copyleft_trolling?"></span>Victim of copyleft trolling?<span data-mw-comment-end="h-Victim_of_copyleft_trolling?"></span></h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Commons:Copyleft_trolling&action=edit&section=15" title="Edit section: Victim of copyleft trolling?"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span><!--__DTELLIPSISBUTTON__{"threadItem":{"headingLevel":2,"name":"h-","type":"heading","level":0,"id":"h-Victim_of_copyleft_trolling?","replies":["h-Resources-Victim_of_copyleft_trolling?"]}}--></div> <p>This page is primarily concerned with steps Wikimedia Commons can take to <i>prevent</i> or <i>minimize the harms</i> of copyleft trolling. If you have received a letter demanding money for a license violation: </p> <ul><li>Read the letter carefully to understand the specifics of the claim.</li> <li>Verify the claim. Does the person/company asking for money actually own the rights or represent the rights holder? Search for information about the entity who sent you the letter to try to verify it isn't a scam.</li> <li>Fix the problem immediately. That might mean removing the image (as described above, with older Creative Commons licenses if you continue to use the image after learning about the violation, you could be sued again). It could also mean fixing the way you credit the rights owner.</li> <li>Keep records of all your interactions.</li> <li>If you decide to pay a fee, you can often negotiate the amount demanded, which may involve explaining your situation or intentions, offering to correct the use, issuing an apology, or some other means.</li> <li>For legal advice, consult a lawyer or seek <a href="https://en.wikipedia.org/wiki/legal_aid" class="extiw" title="w:legal aid">legal aid</a> if available.</li></ul> <p>Unfortunately, we can only provide these best practices and <i>cannot provide legal advice on Commons</i>. Here is what the Commons community <i>can</i> help with, however: </p> <ul><li>If you suspect a license may have changed since you initially used the media, we can help you to look through the <a href="https://www.mediawiki.org/wiki/Help:History" class="extiw" title="mw:Help:History">page history</a> to look for changes since it was initially uploaded.</li> <li>If you suspect copyleft trolling, and not just a single enforcement action, you can share your experience in a venue like the <a href="/wiki/Commons:VP" class="mw-redirect" title="Commons:VP">village pump</a>, bringing the behavior to wider attention. Such reports may not help your case, but form the basis for the community taking action against those who deploy unethical practices, thus helping to ensure others don't fall into the same trap.</li></ul> <div class="mw-heading mw-heading3"><h3 id="Resources" data-mw-thread-id="h-Resources-Victim_of_copyleft_trolling?"><span data-mw-comment-start=""
