Flash exploits........?

It seems good in theory change you ip, but it does not really work, when you sign on they can see other things from your computer. That's why when someone gets kicked off ebay, that's it. I use to rent a server for online game called medal of honor, if I banned some one, and they signed in under a different ip I was always able to stop them. You can not make your self unbannable, but depending on how they have the chat room set up you may be able to fool them. If they have it set up right, then forget it.
