Apart from the obvious one - the censorship and the recent bans, what annoys you about current Reddit?
For me shadowbanning felt the worst. You carry on using a site, posting comments, being non the wiser that no one but you can see it. Felt like a foul/cowardly way of banning someone. An outright honest ban would have been better.
Also anyone encountered being banned due to posting saidit links? I've been posting link to it on the /r/RedditAlternatives and subreddits where the refugees from the banned subs congregated and first got my account shadowbanned and then banned with no messages from admins.
