That dead woman called Tumblr is still walking with a healthy strut these days, also soaking up some displaced Redditors. Horny shit is slowly but surely returning to Tumblr’s fields, as well.
Tumblr illustrates the problem with porn in general, they didn’t shut it down for no reason, they shut it down because the pedos had decided to use it as a dissemination portal for their vile shit, and the structure of Tumblr made it difficult to moderate away, especially at scale. Thus, Apple threatening to pull them from the app store, for good reason. All they could do was go scorched earth on porno.
So that’s the issue we’re going to have, here, and I’m not sure if the “some guy running an instance for the fuck of it” model is prepared for it.
