I'm sorry to bother any of you guys, but I really need to warn you all about that guy.
He tries to "befriend" people and then he goes ahead and steals your art without asking. And when you confront him about it, he hides your comment and deletes the deviation. And then he steals your art again and the cycle keeps going around and around until he blocks you.
Don't let him join any of your groups. He joined DDR-Lovers (I think thats the name of it) and he went ahead and stole most of the gallery works and tried to submit them as his own. And he made a journal saying he was "sorry" and he told the group to adminify him.
He "aplogizes" a lot. They're all fake. The whole ruddy lot of them. He just wants to play victim and he wants to seem innocent. I've seen comments and notes that expose his true nature. The group that I mentioned up there, he sent notes and comments to the group members saying "Fuck off Im better" even when he's nothing but this pathetic art thief who's so pitiful that he can't pick up a pencil.
Don't let him on your profile NO MATTER WHAT. He says "hi" to you, then he starts watching your watchers and friends. He does this so you go to his page. It's a popular technique with most art thieves, they watch and fave a lot, you go to their profile to thank them, and there's their huge gallery of stolen art that might appeal the untrained eye, and even if you don't fall for it you're another pageview.
If he watches/faves something of yours BLOCK HIM. This act is simple, just go here www.deviantart.com/settings/id…
and fill out the rest. He's dangerous and if he gets to know you to well, or maybe if he just sees that you're a good artist, he'll grab your entire gallery and run off. And he'll delete it later.
He likes to compliment a lot, to build up your trust, then he runs off with the pictures. If he appears at all to you BLOCK HIM OR YELL AT HIM.
Another random side note: He takes your art and mixes it in with other backgrounds, I don't know how to describe it. Just know that he's an art thief, and you should either block him or warn others or yell at him. Maybe if enough people tell him that what he is doing is wrong he'll get a hint.
