Fr3sh, LFJ and ESPECIALLY Joker should not be allowed to play whatsoever, it should be a dead giveaway to not allow them by now, better off playing shorter game then with blatant saboteurs.
The rest you mentionned Klin, were just inactive/bored participiants, like Jasper or the Milan fan, but not done anything to be disqualified in behaviour, unlike the one you just allowed because you need players.
Just my two very obvious cents.
