Kick player doesn't do anything, as there is a single queue. Imediately troll click join and gets back to the same lobby completely locking custom game queue.

There is a person with VAC bans. Has been making own lobbies, then dislocking them forcing other player to waste time and leave. Then he was disapproving the game and rejoining back. Then he was teleporting other players to locked zones with KOTL. And it's not a first time. Either kick player from lobby should ban him for 5-10 minutes or there should be an option to ban player at all.
