I just personally witnessed an abuse of the thumbs-down feature on another forum that I read, where each click deducts a point from the user's reputation.

Two adults got into a childish argument, and one of them thumbs-downed every single post ever made by the other one. The psychopath spent DAYS doing it, apparently by hand on each individual message. The victim had ZERO reputation points when the attack ended.

TL;dr - it isn't worth the headaches.....
