There’s no one thing that defines sex, that’s what makes it so complicated.

There’s also a large AI blocklist for uBlock origin if you want to try and block AI slop sites from search results: https://github.com/laylavish/uBlockOrigin-HUGE-AI-Blocklist
Someone posted it here the other day and I love that someone’s gone to the effort to compile it.
