Vispilio is on DT1 and Vispilio has added Cacingkemi is on his/her trust list as a result Cacingkemi is now DT2. Base on the trust history of Cacingkemi, Vispilio should remove that user from his/her trust list. Otherwise other DT users should remove Vispilio from the DT. I don't think any other option for it. If anyone like Cacingkemi is on dt list then that will be a bad effect for the forum users.
Vispilio is backed by an army of.. questionable accounts, many of them having negative trust. And some of the accounts from that "circle" seem to become DT now ant then.
So I don't really think that he will care to do anything. Of course, I'd be happy to be proved I was wrong.
