Me and my friends have been using these all weekend, and no ban yet. I think it's probably because we haven't used the teleport feature, or used the hacks to gank/troll others, only to defend ourselves. Play nice and be as incognito as possible. Other people can see you teleport, then you get reported and that's when the bans come. Play it safe, don't be an a-hole, and you should be fine...
