Back in the v2 days the "thanks" added rep. I know why they did away with the "thanks" and turned it into a "like." They even tried to limit how many "thanks" you could give per day. It's part of why so many old members with low post counts can have huge rep because it was so easy to get "thanks" back then. I think the "like" should at least count for something towards your rep. Say like, 200 "likes" minimum could equal 50 reps or something, but I digress. A thumbs down or dislike, like the "groan" did in v2 took away from a users rep. The report button is used best for bad posters. Honestly, if I saw a "
IMAGINE dis-likes this" under a post, I'd rather he post about it so I could know exactly what he disliked about it.
