To directly answer your question, my guess is they have an alert set up for various places on the internet, and are able to post the links faster than anyone else. Maybe that part is automated.

AI product updates probably tend to rank very well here. If you look at the domains the user is submitting, they’re pretty normal: twitter accounts of tech CEOs, big company blogs, etc.

If I saw a bunch of blogs with affiliate links or landing pages for slop products I’d be more suspicious.
