I feel like this article may be a bit unfair. It sounds like organically a community wields a large number of votes, and they aren't getting the same treatment as other communities on Reddit?
Did you even read the article? They are being targeted because they are engaging in vote manipulation. Members of other subreddit don't collude to upvote everything and try to get into /r/all. They also don't go and attack other subs. Also, the racist and sexist nature of the posts makes it inappropriate. Reddit has already taken a stance against this sort of content when it banned a bunch of subreddits a few months…
Is censorship of "inappropriate" speech the right precedent?
