I literally have an account there dedicated to porn. Have had it for years. I stopped using Twitter after the muskocalypse, except I still check my porn account every once in a while.

You have to actively go looking for porn there, but once you do it's a neverending rabbit hole. Especially if you're into some niche/fetish stuff. There's some unique stuff to be found there...

There is tons of porn on twitter since a long time. They somehow managed to keep it away from "normal" twitter. That is why it worked. That has been eroding for a couple of month now with the "invasion of the porn-bots". If they don't manage to continue to separate the porn-twitter from the non-porn twitter I don't think that will end well for them.

I've never used Twitter, but my partner does and regularly comments on the quantity and quality of porn there. It's my understanding that another popular social media app banned porn a few years ago and all of the porn moved to Twitter.
