I've tried (and failed) to delete my Facebook a couple times in the past, so this most recent go, when I quit using Facebook, I just quit using Facebook -- I uninstalled the apps from my phone, and mapped 'facebook.com' to localhost in my /etc/hosts files. The result was... amusing. Facebook kept emailing me the "Hey, did you see what so and so posted?" emails, knowing full well that I didn't see them. But then, afte…
This is such a weird thing to think. You can turn off all notifications and they'll never contact you, ever. I stopped using Facebook 6 years ago and haven't gotten a single email / sms from them since then, because I used the settings properly. Yeah, if you just ghost them and never click "update your email settings" at the bottom of every email they send, they'll keep sending them.
So I feel the GP's pain, I've taken to marking them as spam as well because I know that my settings aren't guaranteed to stay where they are. It's not even in Facebook's best interest to try and keep my notification settings where they are.
