The difference between that subreddit and fatpeoplehate just seems to be the fact that one is just posting neutral content while the other one is hate/bullying focused. Most of those other subreddits also seem to just be almost purely content based, which as far as I know has legal content, or at least content that contends with Reddit's rules and has not been taken down by a legal entity. Others are just mostly dead and have about a post a month or even less. The others that are actually racist I have no idea about - I guess they're just not very big so they don't care. I'd imagine they banned FPH because it actually had an effect on the "community". As far as I can tell that's the main reason that banned the Vilecruz subreddit. If it never got as big as it did it would have remained unnoticed. I don't think Admins are subject to some type of rigidity in their decisions despite their hilarious attempts to establish what their "rules" are. At the end of the day they can do whatever is best for their website for shareholders - everything else is secondary. If any of those above subreddits become a "problem" I guarantee they will ban them regardless of how well it regards to their rules or not. I sincerely doubt a website like Reddit has integrity to go against major media.
