Custom ULX command help

So my server is running a new Jailbreak gamemode and I would like to be able to ban a player from joing a specific team, how would I go about this.

Well, I have seen on the internet that their is custom ULX commands such as for my ttt server a option to slay Next Round and to respawn players. I bet that their might be something somewhere like that or you can go on coderhire.com and get someone to code it for you (by the way wonderful website). I am a fan of jailbreak and I think this would be useful as well. Good luck!

You should use the PlayerCanJoinTeam hook.
