"I was trying a trick that a friend gave me." - This should never have happened in the first place, upon registering and logging into your character for the first time you agree to the Havoc-WoW Rules and Guidelines which explicitly express that we do not condone any sort of hacks on this server. The fact that you claim that you were trying a trick your friend gave you doesn't explain the fact that you used the hack to kill multiple bosses several times, instead of just once or twice if you were "trying" the trick. This behavior shows me that you were content using the Hack and had no sense of stopping.
All the information that we can gather in-game leads to the conclusion that you're most likely the same person who's already been banned : 7 days, 31 days and then finally permanently, We are not responsible for what your friend does on your internet, however you should be if you don't want to be associated with such a person. In short this IP has been caught hacking for the 4th time.
The ban will stay, I wish you a pleasant day.
