Okay, just going to keep it simple here. This is a public teamspeak, not a private one. (In the sense that anyone can join and use it)
What this means is that it will be a place where all sorts of people get together, most from our community. It is not rare for people to butt heads. It's not rare for people to develop bad feelings toward each other. But this is a public server and for that reason, we expect you to have some level of maturity to deal with bad relations on here in a manner that we do not need to step in just to tell you not to be rude to each other. If these people continue to harass you after you have made an attempt to ignore/block them, we want you to report them and we want to take action against them.
So please do report them. Do not make that attempt to ignore them and then not report them after they continue to harass you.
As for Hannibal, none of us saw any text come from you that proves what you just said. You were banned from a public channel under suspicion of doing something underhanded which we have had experience with before. Just because it was a public channel, does not mean there are no rules in these channels. There are rules for the teamspeak in general which apply to these channels. We gave you a chance to reply and prove to us that you weren't up to no good but you never did and that warranted the ban.
