Reddit is purging NSFW subs as well as trans-related subreddits
And a screenshot of the post on Reddit, from which the meme is quoting:
Brace for Rexxit 2.0. This is not drill! Granted, most of the Redfugees will be going to Lemmynsfw (I helped by dropping a link in, we'll see if that lasts) but as long as we get them out... I suppose you could call it missionary position work.
Ask Tumblr.
Ask Betamax
Ugh they could have named it MASTER-Betas!
Ask HD dvd
Tumblr is still populated and widely used
Just like your mom
They also let porn back on Tumblr
Still kicking and full of porn
That's kinda my point, they did some token banning, people got grumpy for a bit then carried right on.
