I've previously marked V_V as a probable troll. It seems a lot of feeding is going on. This post in particular is not an appropriate place for it. I'm thinking of adding a term to the Deletion Policy for, well, this sort of thing on any post that reports a positive community effort - see Why Our Kind Can't Cooperate for the rationale.

When I was doing OB and the Sequences, I realized at one point that Caledonian was making it un-fun for me since each post was followed by antihedons from him, and that if I didn't start deleting his comments, I would probably stop continuing (though I certainly didn't know as much then about reinforcement psychology, I still appreciated this on some instinctive level). I'm not going to tolerate that kind of negative stimulus being applied to community organizers.

I think it might actually be a good idea to give any poster the power to delete replies in their post's comments thread - Facebook does this automatically and I don't think it's a problem in real life, except of course for the trolls themselves - but that would require development resources, and as ever, we have none.
