Add censures (hmm I think I spelled it wrong) to it like heres example:

Random1: LoL U suck!
Random2: I wont! F*** you!

And then if u want u can make it like this:

Random1: LoL U suck!
Random2: I wont! F*** you!
ServerBot: Autokick 5 minutes..
Random2 Disconnected from server. Reason: Kicked for 5 minutes
