Animation Source Forums

I'm going to link a helpful deviantART group to this topic:
http://artthieveslist.deviantart.com/

This is a group that helps get the theft out there and well known, as well as having the chance to get several reports on the theft which increases the chance of the art being taken down.

While this topic is good to get these thefts out there, that group is also a good addition.

Not to mention stolen linearts, half of the drawings are traced from Mushy and Deni...
