FWIW I just reject any outgoing attempt to these range from my firewall using a file I version and update once in a while.
EDIT: I've also got a PiHole running and I'm pretty sure it's also blocking a huge lot of FB related ad domains.
I could automate the whois query and check if it's different from the current list I'm using but I don't bother (so far).
whois to find all their IPs range and block all these? They change once in a while but not every day.
See here for the whois command:
