So you are telling me you think it is completely normal behavior for someone to *ask* to be removed from everyone's trust list, and continue sending trust ratings? These two activities conflict with eachother; there is no argument against this.
Maybe he doesn't want the hassle that comes along with having his red tags (or green ones) carry so much weight.
I thought it might have something to do with the realization that he was providing support to those who were promoting scams he claimed to be fighting and him not wanting to be a complete and total hypocrite while maintaining his personal relationships.
