I got shadowbanned simply for linking to saidit.net. After I joined here, I reposted a highly-upvoted comment of mine (that summarized the history of censorship on reddit) from saidit onto reddit, and before the day was done it had been deleted by mods.

It's probably best not to go onto reddit if you don't want your brain to be warped by an incredibly distorted discourse. You'll think it's normal to think the kinds of things reddit mods and admins think about. Believe me, it's not normal.
