Afaik, tagging at trust-feedback only for users who broke the trust rules (in general behavior): what happened, who is he/her, and how it happens; especially for trading, monetary and security system. And DT members work in this area.

For the user who broke some forum rules. I think it's clear enough that users should get sanction/punishment, terma/permaban from the forum. And this is moderator should do so.
