I wanted to clarify something for the mods and anyone else that is reading, since I had received a PM about it. The two instances I referred to were both certainly a prank, one a malicious one and the other one perpetrated by (I think) a friend of mine (and it was hilarious). I know even a custom avatar can be copied once it's on here, and has been. It's simply that if the avartar in use is removed from the list, it won't be used innocently.
