I know him, he's a loser who's been on Deviantart since the early 2000s and he's in his 30s or 40s. He is constantly asking for weird requests with a lot of detail and always involving weird fetishes (some are passable like transformation and fat, but others are weird like a head getting smaller than an acorn) and he asks these things for everyone, not just furry artists. He's already been complained about on Deviantart, but he hasn't called blocking people who criticized him.
