Reading up on the latest policy change, it seems to be a major overstep. While they clarify they are not blanket banning any species, there are specific species they are flagging according to many artists just based on the characters natural proportions (i.e. Impmon; impmon, on model, has "childlike" proportions, and it therefor not allowed on FA).

Leaving it to something as vague as moderator discretion and proportions seems an odd choice. Unfortunately it looks like it'll be easier to just follow the artists elsewhere than maintain FA as a central point. Ah well.
