Good day.
The following is a problem we rarely encounter, and when we do, most of the time we can resolve it on our own. In this case your help would be really useful, or some advisory at least.
Recently we found out about a person who exploits SCP Foundation materials commercially, violating the CC license - the SCP Wiki commercial license as well as the Russian Wiki non-commercial license. Simply put, he charges a fee to voice translated SCP Wiki articles, as well as Russian-authored articles, and to create visuals for such audibles. According to the data we've acquired from social network users, this person has been doing it for quite a long time; a price list exists for his services. The only attribution made amounts to a link to the Russian site, or to the article in question. In both cases this does not comply with CC license requirements.
As far as we understand the licensing, the only way of using the materials in a commercial fashion is voicing English articles in English, along with a link to the source page, a mention of its author, and a disclaimer or note stating that the article is published under the according license. Every other commercial usage of this sort is illegal and violates copyright. Granted, if this person would translate the articles on his own, without using any materials we've published, that would have been acceptable, provided every other CC license requirement was met.
As for Russian-authored articles and translated articles, Russian Civil Codex, part 4, article 1260, paragraph 1, states the following: "The translator, as well as the author of another derivative work (adaptation, cinematization, music arrangement, stage version or other similar work) has the copyright, accordingly, to the translation or other derivative work based on another (original) work, that they authored." In other words, translated SCP Wiki articles are protected by the Creative Commons Attribution-NonCommercial-ShareAlike 3.0 used in the Russian branch, which makes commercial usage of the translations inadmissible. Same goes for original Russian articles.
We need your help with this problem. We address you mainly because a department for this kind of problems exists in your site, and because you have the experience. Your advice in resolving this situation will likely help us handle it with minimal reputational losses and help developing international relations between our wikis.
Respectfully yours,
Russian SCP branch administrative staff.
