I get the reasoning, but I do feel that the rules are Way too strict on artwork (as opposed to pics/video of real people) to an unprecedented level. I'd like to see that reevaluated to be more in line with what other sites that allow NSFW permit - if they were facing legal trouble over that content, then they would ban it too, so I think it's pretty evident that they don't.

In particular this whole concept of establishing a "canon age" for every character and disallowing aged-up art strikes me as much worse than simply disallowing any art that looks underage.
