Most posts from what I see are now ‘’meme’s’’, ‘‘I justify pirate because…’’ and ‘’This is my collection!’’. Pretty much just hurr-durr look and upvote me kind of content.
/r/piracy wasn't much different in that regard when I unsubbed from it, long before leaving reddit last summer. It happens anytime there's a large enough userbase, as that sort of content is easier to create and consume, the latter making it more likely to get voted up.
