That's simply not true, especially in flagrant cases of abuse of the system. Another thing is cases where for a personal matter that has little to do with trading risk, two DTs end up red tagging each other, and things like that, where the community simply waits for them to resolve the differences between them and end up deleting the tags. But if someone flagrantly misuses the trust system they end up massively distrusted, so out of DT.
