Replaced Messenger with Signal. Blocked all Facebook domains, even Instagram, (so many!) in my MacBook's etc/hosts file to "blackhole" any FB tracking. Can no longer sign in on my laptop. Still have Facebook on my phone with Location privileges turned off. This has corresponded with increasingly aggressive notifications on my phone about things that don't directly involve me. I used to I only get notifications about things I posted on or posted myself. Curious if this has happened with anybody else who disengaged.
