What about this?

Code:
on *:join:#: set -u60 $+(%,60sec_,$nick) 1

on *:text:*:#: if ($1- == don't ban me) && ($($+(%,60sec_,$nick),2)) kick $chan $nick


Make a variable with the persons nick that is unset after 60 seconds. When something is said check if it's bad and that nicks variable still exists
