Sadly, there's nothing GASR staff can do about theft on IMVU. If the user is a member of GASR and/or you see her selling these same stolen display pictures, you can report it to a mod and they can keep an eye on it, but that's about it.@Mar @Tetsu
If you know any of the original artists, try contacting them or tagging them. I know that blue haired DP belongs to Eat@IMVU. Also looks like @poisonous
made it as well, not entirely sure tho.
