- A bot that automatically removes users' posts and comments without actually banning them or telling them the items are being removed (this is a subreddit-specific "shadowban", though it's not a built-in feature of reddit it has the same effect)
- Moderators that eagerly attempt to ban all dissent, not only from their subreddit but from all of reddit
They are both wrong, both unforgivable, and both forms of censorship. Just ban people you don't like from your subreddit, no need to code custom bot features or try to lie to the reddit admins to accomplish political goals.
