You could use it, but would it be the most natural thing for you? Or are there better tools for that task? The nyaa source code includes features and organization specifically for the anime/manga scene.

For example, there is torrent classification to detect whether the torrent contains an entire series, which subtitles it contains, whether it is a reencode/remux/scene release, etc [1]. Would that be useful for you to host legitimate content (which typically is not reencoded/remuxed/fansubbed)?

I am all for criticizing the chilling effects if the DMCA was targeting the DMCA protocol in any way. But in this case, it is targeting the source code for a CLEARLY illegal website (illegal, in this case, based on the jurisdiction in which github operates and is bound to)
