Hello,
I hope this is the right place to ask, if not please excuse.
All files uploaded to MediaWiki.org must be available under a free license (no "fair use" or "noncommercial"). What we do with files with unclear copyright status (no license, no author, etc.) such as:
* https://www.mediawiki.org/wiki/File:Scott_profile_pic.jpeg * https://www.mediawiki.org/wiki/File:EMWCon_Spring_2016_Mediawiki_in_the_Ente... * https://www.mediawiki.org/wiki/File:3d_extension_screenshot.png * a lot of other
Nominating for deletion? Per the intro at https://www.mediawiki.org/wiki/Special:Upload such files must be deleted.
We have {{Unknown copyright}} template, but it seems that nobody is working on it?
Best, --Steinsplitter
