alot of times, its one of those situations where nothing can be done.
pushing the edge of the rules without actually breaking any
so warning
and it happens again soon as you leave, and you end up with 4 new reports for the day.
Well I can't really say much here without a specific example. If the rules are being stretched by one person to simply annoy others and make the game unfun, they will eventually be kicked too. (it really depends what it is that's happening though)
Like, for racism and shit, I don't hesitate to kick. One quick warning, if they keep doing little subtle things that will offend people, they'll still get kicked.
