Cross community censorship: For example on Reddit you wrote a comment in subreddit A (maybe even a negative one for that topic!) and then subreddits B, C and D permanently ban your account. If someone starts with that crap again they should be shunned.
Oh and verified users only communities, that sucked too.
I've never been called either in nearly 12 years on Reddit (and being plenty active with ~120k comment karma).
Maybe if you often get called that you should re-evaluate your opinions?
