The most prominent removal — or, as the admins say, the only subreddit with more than 5,000 subscribers — is r/fatpeoplehate, a forum devoted to posting (among other things) pictures of overweight people for ridicule. A follow-up comment lists the other four subreddits as r/hamplanethatred, r/transfags, r/neofag, and r/shitniggerssay; they’ve all indeed been shut down, all but one “for violating the Reddit rules to keep everyone safe.” According to the admin, these last four ranged from 149 to 3071 subscribers, although in r/fatpeoplehate’s case, “more than 5,000” is a bit of an understatement; the last Reddit metrics (and a Google cached page) put it at around 151,000 subscribers.
If Reddit’s closing down all the fun sub-reddits in the name of political correctness (which it is, Ellen Pao is very SJW) then that’s a market gap for someone happy to epater les SJWs.
So, how tough is Reddit to replicate as software? Is it based on a box solution, like Wikipedia? And who has the cash to throw at this?
