I also agree with Little Mouse's statement about giving a negative vs. excluding someone from your trust list in a case like Timelord2067.  If my memory serves me correctly (and it may not), before I wiped my trust list clean and left it with just ~DT, I had Timelord2067 excluded. 

My opinion is that he has good intentions as far as helping the forum goes, but he tends to see connections between members/accounts that sometimes are preposterous--and he's left enough questionable or flat-out wrong feedback for people that he probably ought to be excluded from DT on any level, indefinitely.  And it's not that I don't like him, either.  We've exchanged friendly PMs in the past, but being on the DT list gives a member a significant amount of power over others, and that power should be used judiciously. 

So if Timelord2067 isn't on DT at the moment, what exactly is the problem here?  It sounds to me like the other DT members have done their part in suppressing his potentially damaging feedbacks, and that says to me that the system (however broken or imperfect it might be) is functioning as it should.
