This is going to come off as crass, but you should probably learn to grow a thicker skin in both the gaming world as well as the internet in general. If you are expecting people not to act like badly behaved, immature children ...or, when they do, you are expecting that they will get punished for it ...you have a real-life awakening coming to you.
The difference is, here they signed an agreement to act appropriately. So, yes I do expect them to do so.
OP, report the name. If it passes their investigation, it will stay. If if doesn't, that person will be forced to change.
