I don't think marlboroza, what I believe amounts to pretending to want to get off DT2 is suspicious on its own, but he was in fact blacklisted from being on DT1, and was removed from DT1 immidiately.
This is a fact? Maybe I missed something, but could you provide your source?
I'm surprised you dropped out instantly, does that mean you can drop from DT1 the moment you don't have 10 users on your trust list anymore?
I don't know, probably not, probably on voting day. Blacklisted on request

You used to be DT1. I'm surprised you dropped out instantly, does that mean you can drop from DT1 the moment you don't have 10 users on your trust list anymore?
Is this the intended behavior of the system?
I posted why I believe marlboroza is pretending to want to be removed in the post you quoted. You used to be DT1. I'm surprised you dropped out instantly, does that mean you can drop from DT1 the moment you don't have 10 users on your trust list anymore?
What's far more likely is he was just sick of the petty drama of DT politics and wants to take a breather from it.
It is possible he does not want to participate in DT drama. He opened a thread asking to be removed from DT2 on Feb 11, and within 10 days, by my count, he had left an additional 50 ratings, and in the ~month since he opened his thread, he has left more than 120 ratings. The above happened when he was very well aware that he is still in DT2.
Based on the above facts, I don't find it to be a reasonable conclusion that he was trying to get removed due to the DT drama.
