I remember seeing people getting worked up over downvotes in some of the smaller subs over at reddit. A lot of the time they were just seeing the vote fuzzing that was happening over there, and panicked about it. I hope Snapzu doesn't end up having to resort to that kind of thing, but overall I don't think Snapzu is the kind of community that elicits "brigading" and whatnot, but that might just be a symptom of it's smaller size. Only time will tell, and here's to hoping for the best!
