User blog comment:Jetgoshi/Is any Mugen character allow to be on wikia?/@comment-3572662-20120330144028/@comment-3495717-20120330163951

That could be refering to certain things like The Black Heart, or other gore-style images that younger children would perhaps not want to see.

Pornography is completely against Wikias policy anyway. If someone wanted to, they could create a MUGEN Database for hentai characters and whatever (I personally would not want to be part of it). Perhaps "MUGEN Database: After Dark"; who cares if Memebase uses that :P

The only thing with that idea is that it would have to be its own Wiki, and not on Wikias network.
