It happened to me today. I wrote a comment on watchredditdie because it hit the front page. I was banned for participating in a hate subreddit. I had no idea that it was a hate subreddit. I actually deleted the comment before seeing the message from mods saying I was banned. All I wrote was something like "meh I don't like gore so I never liked watchpeopledie". That was it.

Honestly, they can keep me banned. If they think what I did is participating in hate, then they're too fucking sensitive or stupid and I am all set with not being subscribed to them. I know it was an automatic thing, but that makes it even worse. They don't even look at what we write. They just accuse us of hate for no fucking reason.
