Would you rather more strict moderation? Though, even three or two years ago, users interested in 2D art didn't really post, comment or vote that much.

The issue may be more photorealistic rather than 3dcg. I'm really annoyed by the fact that the photorealistic tag is not being used when it certainly applies to the post, because that shit should be easily filterable without blacklisting 3dcg outright. If I search for 3dcg -photorealistic, I expect not to see them, but that's not the case. Doesn't help that they attract so many annoying autists as well.

I've actually been considering banning photorealistic posts despite my affinity to some of them.
