While I have been building my little program which works like this: Little imvu hack.
I discovered a client crash bug. I did not digg into it deeper, maybe its a possible code injection opportunity :p. The trick is, you enter to chat with huge user ID number (9483985934589345934) and send whatever text you want. Imvu client crashes right away.
Oh and as you can see from the picture, you can be whoever you want on imvu. Even imvu inc itself.
Doodlez!
