Personally I don't think people should have their comment voting rights removed, without being told, unless they're really causing trouble. And even then, let them know so they can adjust their behavior/leave.
This sort of thing just kills communities IMHO.
Mine is at 1.91 and I can't vote so that would make sense.
BTW I seem to be able to vote again now. Thanks pg! kinda nice... Though now I feel the weight of responsibility again. However, the big OCD thing is that now the UI works properly! I really like that. And, no longer being a persona non grata (an exaggeration; I could still comment and vote on submissions).
Odd: my average is precisely "2". Not "2.00" (as it is for robg, #6 on the leaders). Have you kindly promoted me, or is it just an coincidence (and you're using different formatting)?
EDIT my average should have decreased with this comment score at 1, but it hasn't (unless there's lag of course).
