Since I am out of loop - my bias is still: why wouldn’t (furry) porn be profitable? :D

Porn on tumblr was an early victim of credit card companies not wanting to be associated with that filthy filth, like what happened recently with videogames. Iirc, they pressured app stores to take the tumblr app down.

as a long time tumblr user it’s so very ironic to me that short after the 2018 porn ban you see the rise of fan sites, and still after that tumblr tried to monetise by adding tips, and various ways to pay your favourite bloggers and just… you already had users willing to post hot original porn, and later you had ways to monetise it, but no, they did it in the wrong order wtf
