A group of online TeamSpeak hackers who professionally go around and destroy gamers TS's. Many of these people are young kids and older immature adults. From pictures seen of them they are mostly comprised of gothics and fat people. (no offence)
In this definition I will give you the #1 way to avoid being caught in the -k0s- trap.
They have 1 signature move that catches any non-exploiter educated person off gaurd. They have modified there TS (which directly routes to yours) to have the ban button give them SA (server admins). But that is the start, it's how they get you to ban them is the part many people don't expect. They somehow have embedded in the coding when they login that they are registered and already have SA. But don't fear, they don't. This is just a ploy to get you to right click there name and ban them.
How to stop the goons: First thing is education. You need to know what to do when the occasion happens. The number one method of securing yourself is to put a password on your TS and make EVERY channel moderated so they must require Voice Rights to talk. Better yet, have all channels except lobby password protected so they can't move around. And the last thing is to make the room allowed in lobby low so they can' spam logins.
I can guarantee the only true way to get rid of one is to ignore them, let them have there fun in the lobby. The second (and not tested fully) method is to right click there name and hit "G" and write there IP down and then...
