Yeah, it's more insidious than that. I've been a heavy Reddit user for 7 years. The situation on most subreddits is now basically all comments being moderator-approved at a fine level of detail. They just do it after the comments appear, giving the impression that free discussion is still happening. Which comments and threads are allowed to persist is becoming very obviously narrower over time, all over the site. There is daily consternation among users over it.
Agree or disagree with the politics otherwise rampant therein, subreddits like /r/KotakuInAction seem to do a good job of cataloging some instances of this (ex. [1][2] and basically anything else in their [CENSORSHIP] tag/flair). Granted, this is likely not the best source, due to the fairly political nature of such subreddits, as well as that I haven't checked many of these to verify the accuracy of them; I just occasionally like to see what different sides of the debate(s) are up to.
