It's really weird, because I ignore the username sended for the chat init... I only get the userid, and I get username and clan tag from the database so it's really weird that it works :/ I've tested it on my computer and it doesn't workQuote:
I am sure it is Not clientside. I have my program which "fakes" the name and a normal Client on a other account Running all the time when I do such things. And the users "reacted" to it aswell.
