There are also a lot of rather large subs like /r/shit____says that serve as downvote brigades to harass people over their opinion. It's online-bullying at its worst.
Well duh, hence why fatpeoplehate got banned and shitredditsays stays because they're pretty much the same subreddit, except the latter actually breaks the rules.
Except for that time that fatpeoplehate doxxed the staff at Imgur on reddit when Imgur no longer tolerated FPH posting images of fat people to laugh at on their servers.
Context is important.
