Do you know which domains one would need to block?
facebook.com
fbcdn.com
fbcdn.net
fbsbx.com
fb.com
instagram.com
WhatsApp can work without these, but maybe a smaller subset would suffice. NextDNS[0] for iOS can be used for the blocking.https://github.com/confirmedcode/lockdown-ios/blob/master/Lo...
