Colour me unsurprisinged. For my sins ( mostly for the sin of being helpful and knowing my way around computers) I have ended up as a moderator of various Facebook pages (for nice enough causes), and the last year there has been a stream of scam attempts. They all claim to be Meta and threaten to delete the page - mostly for alleged copyright violations - unless you follow the link...
I of course block and delete (to avoid anyone else of the moderators falling for it), but it's quite obvious that Meta doesn't care that scammers impersonate them on their own platform, or they would have done something about it.
So I find this par for the course.
