But that's got to be what you're searching for. I forget that there's any porn on X, and for a fairly long period I actually thought they had banned it.

Yeah, this is such a tired lazy response by people and is definitely not true anymore. Spin up a new account on a fresh device on a network I've never been on. Click a random video and scroll. Usually the first 3 or 4 scrolls is porn or someone being killed.

Anyone saying there isn't an insane amount of porn and worse on twitter is either lying or hasn't been on the site since it turned into the cesspool we have today.

I think it must be that porn often ends up being the most likely relevant content in the randomized initial state for a lot of algorithms. It then shifts and focuses into your actual liking as it collects more data. That should explain a lot of these phenomenons.
