Maybe limit the number of "voting points" you get per day based on your karma? Works great at Perlmonks. Whoever it was went through my posts as well. I just figured I had pissed someone off with my Disqus post :-)
Sure enough. It was the same guy. I'm not going to out him, because he has contributed significantly to the site, and I think this was just a lapse of judgement but please do not do this anymore.
