If you have a regular WoW account, do not use any type of hacks\model edits. I was chatting with a GM today(sorry I have no pictures to prove this) and even though I was on a trial account and running a proxy and had cleared all of my caches he knew of my other account. This shows that they CAN and DO track IP adresses, and proxies don't help. I am going to deeply miss hacking and severe model editing(like zep to gm island...) I will still do minor edits and stay around the forums however.
