Mods are mods aren't paid, so they use a lot of very broad auto-moderator bots -- many of which are very poorly written. You can get a permanent ban from a Subreddit for having a user name the bot finds offensive, for example. You can have a post removed because you didn't end your question in the syntax the bot was expecting... and even if you fix it, and appeal to the mods, and they reverse the decision, your post gets restored as older and without any votes so nobody will ever see it. It's more that the moderation is an example of bad automation -- I think this is what reasonable users get up in arms about.
