It appears we a have spiteful downvoter in the midst. There was a time when I was against banning people for this reason, so for fear of sounding like a hypocrite I won't measure in. But, I will bring it up to the community to inspect and do with him what they will.

Prisonpanda has downvoted a bunch of gwiz665's videos in a row without prejudice: http://www.videosift.com/member/prisonpanda/voteddown

This is really dumb, because he just finished castrating the lot of us for "policing" the Sift with our downvotes.

I guess the only downvote worth giving in prisonpanda's mind is one he gives aplenty and indiscriminately to gwiz665. Though, in his defense, he doesn't seem like a troll. If you read the majority of his comments, he seems like a nice enough guy. http://www.videosift.com/usercomments/prisonpanda

Apparently, he has offended before: http://www.videosift.com/member/prisonpanda#comment-171580

Do with him what you will, Sifters.

P.S. you can instaban him if you have a powerpoint and type *quality in the comments. Just FYI.
