Reddit has actually started cracking down on things which count as 'objectionable,' lately. From quarantining to outright deleting communities and changing its rules in a way which stunted the smutty subreddits a while back, they've been moving closer to the direction tumblr took. I'd be interested in knowing whether this was related solely to them overmonetizing the site and being afraid of advertiser wrath or perhaps related to the cloud servers - or a combination of both.
