Nothing is quite as satisfying as watching someone who is farming karma getting called out, then seeing them delete their post afterward.

I saw a post about someone making a "controversial" opinion (their words) about liking a game everybody fell in love with. It was a well-known, widely loved, and highly praised videogame that is very good (fires of rubicon). Then, a few hours later, after we called them out on it, they deleted the post.
