Never participated on Reddit....well, I tried once....seemed too...well, big and moved along way too fast for my old butt
Maybe someone here has some experience there....do the mods just sit back and, well, mod? Or do they actively participate? Seems to me, if the latter is the case, some tendencies could form....for or against certain users.
I use reddit a bit, not an expert, but it seems to me that moderation is subreddit specific.
You might have one subreddit, like the feminists subreddits, which are very heavily moderated. Its all about group think and echo chamber, and anyone who disagrees is banned and posts are deleted immediately - *just* for having an unwanted opinion.
Then you might have another subreddit in which the mods running it prefer to let anything and everything go. They will only remove spam and posts which explicitly break the law.
If one of these 'anything goes' types of subreddits gets too crazy, then the upper management might step in.
I could be wrong, but I think people are especially upset about the censorship in /r/news because its... you know... NEWS. Its not "feminist news" or "my look protected echo chamber news", its supposed to be general news - so many feel that the mods shouldn't treat it like their own little private party pushing their own political agendas.
