 | This page in a nutshell: The purpose of this page is to provide a brief overview of the procedures in place for handling text-based copyright violations on Wikipedia. |
When looking at a Wikipedia article, you suddenly spot something that looks like it may have been copied and pasted or closely paraphrased from elsewhere (typically from one or several of the sources), or it looks like a machine translation from some foreign text. What can you do?
Copyvio handling in under a minute
If the entire article is a problem
If the entire article is a problem and any remaining text could not survive, check the page history:
- If the article is foundational copyvio (there since creation) and there's no ownership or permission asserted, nominate it for speedy deletion with
{{db-copyvio|url=URL of source}} - If the article was started with different text, check to see if the copyvio was recently added. If it was, revert to a clean version.
- You can put
{{subst:cclean|url=URL of source}}at the article's talk page to explain your action. - You can alert the editor who added it with
{{subst:uw-copyvio|article}}at their talk page.
- You can put
- If it looks like the copyvio has been there for a while or if it's foundational, blank the article with
{{subst:copyvio|url=URL of sourcet}}and then copy the pre-set lines on the boilerplate template: one to list at Copyright problems, the other to warn the person who added the copyrighted content.
If only part of the article is a problem
- Check the history. If the text was recently added, revert the article to a "clean" version or remove the text and place
{{subst:cclean|url=link to the source text}}at the article's talk page to explain your action.- If you can identify the contributor, alert them by placing
{{subst:uw-copyvio|article}}at their talk page.
- If you can identify the contributor, alert them by placing
- If appropriate request revision deletion of the reverted edits by adding {{copyvio-revdel}}
- If the copied text is too incorporated in the article or the case is too complex for you to feel comfortable removing the violation, blank the article with
{{subst:copyvio|url=URL of source}}and then copy the pre-set lines on the boilerplate template: one to list at Copyright problems, the other to warn the person who added the copyrighted content.
If you have a bit more time
If you are a bit less in a hurry and the article has been tagged for investigation rather than speedy deletion, you can:
- Double-check the source. Look for a specific statement that it is public domain or has been licensed compatibly with CC-By-SA. If it has, you can attribute it or leave a link at the article's entry on the Copyright Problems board to the licensing statement so that somebody else can. Even if there isn't a specific statement, you can check against Wikipedia:Public domain to see if the content looks usable. If you aren't sure if it's usable, you can add a note of explanation at the Copyright Problems board listing for an administrator to evaluate.
- To save a bit of time: Creative commons has not declared compatibility with any software license (GPLv3 compatibility is one-way only). So unless the program itself is in the public domain, any text from the interface of a computer program is likely a copyright violation.
- Identify with what edit the dubious content has been copy-pasted, and mention that on the article's talk page and / or on the article's entry on the Copyright Problems board.
- Once you identify when the dubious content entered, check to see if other content entered at the same time or by the same contributor looks like a problem. If it seems like the copy-paste problem exists in only one part of the article, you can place the
{{subst:copyvio|url=link to source}}template at the beginning of the problematic text and add a</div>at the end of the problematic text. If they added other text, you can check to see if you find other sources that have been copied. - Check the talk page of the contributor who added the content. Are there other warnings? Consider whether it is appropriate to request a Contributor Copyright Investigation.
- You can also click on the link for temporary space and rewrite the problematic text. If you do, mention it on the article's talk page.
Are you an admin? Here's how you can handle it
If the copyvio or the processes for handling them are unclear, you can do the same as above and the admins who work at the copyright problems board will address it.
- Copyvios might be unclear if:
- The source has a license, but you are unsure if it is compatible. (Note that GFDL-only compatible texts imported before 1 November 2008 are acceptable, but texts from GFDL-only compatible sources imported on or after that date are not.)
- The source may have copied from Wikipedia, but there is not enough evidence for you to decide that it is a {{backwardscopyvio}}.
Partial infringement
If the copyvio only concerns a part of the article and has been added in a manner that it can be reverted to easily without also removing non-infringing content added in other parts of the article, handle this as though it were a Complete infringement (below).
If the copyvio only concerns a part of the article that cannot immediately be reverted to (because other parts of the article have been expanded in the meantime):
- Excise the copyvio
- Use the
{{subst:cclean|url=link to source}}tag on the talk page to indicate that you did. - Check to make sure that the contributor (if registered or recent IP) has been properly warned about the infringement and consider whether additional actions, such as a block or Contributor Copyright Investigation is necessary. (See Wikipedia:Copyright violations)
- If appropriate, request revision deletion of the reverted edits by adding {{copyvio-revdel}}.
Complete infringement
Articles that seem to be complete infringements are handled in one of three ways:
- If the infringement is foundational copyvio (there since the article's creation) and there is no reason to believe that permission could be forthcoming:
- process through speedy deletion in accordance with WP:CSD#G12
- If there is reason to believe that permission could be forthcoming (foundational or not):
- Tag the article with
{{subst:copyvio|url=link to the source text}}, list it at WP:CP and use the notification generated by the template to let the contributor know how to verify. It will be processed when permission arrives or, failing that, after a week.
- Tag the article with
- If the infringement is not foundational and there is no reason to believe that permission could be forthcoming:
- Revert the article to the last known good version with a relevant edit summary
- Recover any non-creative content you can (references, infoboxes, ELs, CATs and other)
- Enter the article's history
- Tick the checkbox for the last version before your revert
- Hold the shift key and tick the checkbox of the version where the copyvio was inserted
- Click the "Del / Undel Selected Revisions" button
- In the Revision Deletion interface, set "Hide revision text" to yes, and leave the rest untouched.
- Pick Criterion RD1
- Submit and exit.
Important note: Do not hide contributor names, in particular if you recover any content contributed by others, as you would otherwise infringe on their right to be attributed under the CC-BY-SA and GFDL licenses.
Sample scenarios
- A film stub has a 2-line lead and some cast information. Someone copy-pastes the synopsis from IMDB. After that, one or more editors create sections for production notes and reception, but the synopsis remains untouched. This is a safe case where you could revert back to the stub before the IMDB plot synopsis was added, then reintroduce the other sections (remember to credit the contributors in the edit summary), and revision delete.
- A lazier approach that may violate the GFDL "preserve the network location" requirement: Edit out the IMDB plot synopsis. To notify readers to not use the GFDL license, add {{CC-notice}} or {{CCBYSA4Source}}, and link to the most recent edit with the copy-pasted synopsis, the history page as the author(s), and then revision delete from the recent edit back to the time the copy-pasted plot was added.
- The same film stub gets the same synopsis, and the synopsis is then gradually expanded and partially rewritten, and only the first two paragraphs of the original material remain. Remove the fully copied content, and then check for too-close paraphrasing in the partially rewritten content and remove as necessary. Revision delete with discretion, depending on the amount of revisions and text removed.
- Someone copy-pastes the synopsis from IMDB. It is caught quickly, and rolled back to the revision before the copy-pasting occurred. All subsequent revisions containing the copyvio are reverted and revision deleted.
- Someone copy-pastes interface text from a permissively-licensed program. Double check that the license is either equally or more permissive than CC-BY-SA and allows for commercial use. If the program license is not compatible, remove the text.
Sounds too complex? Tag it with {{subst:copyvio|url=link to source}} instead; volunteers at WP:CP will deal with it.
Tools
Wikipedia has several tools that may be useful in checking for copyright problems.
- Earwig's Copyvio Detector will scan an article against the internet, excluding known mirrors (though not less common ones), and against its external links. It displays a percentage of text copied from the orginal source and highlights copies. It also can be used to compare articles against each other and individual URLs.
- Wikiblame. Accessible under the "history" tab of every page on Wikipedia as "Revision history search", this tool can be useful in determining when a run of text first entered an article.
- User:Enterprisey/cv-revdel – Script to aid in tagging articles for revision deletion.
- There's a list of administrators willing to assist with copyvio work at Category:Wikipedia administrators willing to investigate copyright matters.
