I think the comment you replied to was referring to the fact that when Twitter was taken over the entire Trust and Safety team was done away with. This has allowed child sexual abuse material to flourish on the platform.

The child abuse material problem was much worse before Twitter was taken over.

This. They ALLOWED it to exist. Now it's clamped down on where seen, personally I've zeen zero having used X every day since the liberation.

It was referring to the feature they added where you could give a picture of a child to an AI module and ask it to undress it and it would comply, and millions of people did just that.
