Well, I never used Facebook for any login nor did I ever give them my personal phone number or email because I never had any reason to. I deactivated the account a couple years ago, which doesn't delete it. It would just be nice if they let me recover it, but they don't want that as they'd rather force me to create a new account to get their hooks in.

I also never use social sign in for anything other than using my GitHub account for certain things.
