For reference sake the user has been excluded from DT1, but I guess you already knew that:
He's not perfect. Neither are you.
Multiple instances of attempted blackmail and extortion is more than just being "not perfect". mosprognoz is not fit for DT for that reason alone.
OK, I have reviewed everything and am no longer including mosprognoz. That puts him at -1 now. Verified. I otherwise don't see the relevance of this thread, it's all been said in the other (quoted above).
