Subreddits called news that only shows news from a single perspective. Sure if users only upvote a single perspective that's fine but mods shouldn't remove things they don't like if it's news.
Headlines that don't match the article. That always ends in rage baiting.
I always found the Canada news subs, the only posters were the mods, and everything in there was their political spin on things, trying to push their agenda...
I guess what I'm saying is instances shouldn't be allowed to be an echo chamber for the mods
