Communities: Basically impossible, unless Meta/Facebook has a public list somewhere.
Instances: That will be public, because they have to register the domain somewhere and I’ll also assume that they will actually want people to know which ones are theirs, so their users join those.
Oh there’s a list of all their known domains and a mastodon bot that keeps track of new ones. I run my own mastodon instance and I have everything preemptively blocked.

I truly can’t imagine a world where they do it in secret. They’ll advertise it and slap their branding all over it.
I mean, it’ll probably be obvious, however they end up doing it. Just look for all the trackers and cookies 😂
