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?
It is not normal behavior for someone to not honor this type of request if they believe it is legitimate. It appears those who still have marlboroza do not believe he is making a serious request, and marlboroza has not done anything to correct this, assuming he actually wants off everyone's trust lists (as discussed above, I do not believe this). A good first step to trying to get someone to remove you from their trust list would include sending a personal message asking to be removed from their trust list, and to follow up if they do not comply.
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.
