  I don't use any Facebook services, but when a friend visits my place I see background network activiy in my PiHole from all Facebook-owned apps.

    Did you to examine what is trigggering it? Is because of a shared IP-address or a shared physical location?

      Not really. It's just that tons of Facebook/Instagram domains show up in the PiHole admin page.
