Let the trust system moderate itself. Going around telling people who to remove from their trust under threat of themselves being removed is little more than a loophole to let Theymos personally dictate who gets to join his special little club, and anyone who doesn't obey his directive gets removed. That is not a community based distributed trust system, that is a centralized trust dictatorship, in many ways even worse than the old "scammer tag" days, because now everyone thinks it is distributed. This strategy of trying to moderate trust in any way is a failed one and will only lead to this community destroying itself from the inside out as trolls and scammers leverage it as a wedge against the core of the community.
