Okay so you did the stuff back then, when why bring it back up? You handled it now move on. As for the discord stuff, you would have to just deal with it. At this point in time I do not see you being allowed back in unless you really worked for it. You would need to prove you are not the same person you were a year ago. Considering most communities want to limit drama then that is what happened.

As for the TOS being looser in the past... I have gotten people suspended and banned for as little as kicking me from a dungeon before the change. So if there was visible harassment then they would have caught it and dealt with it.
