Hi, almost 3 days some guys coming on my teamspeak3 with their create channel spam bot, that creates channels very fast, so is there any way to stop this, please help..

P.S. Don't won't to put on guest that he can't do even temporary room, this works, but that's bad for other new clients..So any solution, and is there any working anti vpn guard, because I saw it few days ago on some ts?
