That's a good point, regarding whether, or not, FB actually deletes user data after we "opt out." Another consideration is how, when Facebook started out, users were supposed to actually know, IRL, the people on their "Friends List." I adhered to that rule all the way until my account deletion last January, but now a great number of users have people on their "Friends Lists" who they have never even spoken to in real life. This point is illustrated by corporate entities being on people's "Friend Lists."

As for FB allegedly tracking me subsequent to my account deletion, could someone explain to me how it could be so? I never posted my actual DOB, nor my cell phone, the email address I used to register hasn't been logged into for many months, and I'm using a new ISP - which uses dynamic allocation addressing.

A possibility could be if your email shows up in your friends' contact list which FB gets from their email accounts.

FB continuesly harrassing me to give them my email password - of all things to ask for! - is something I will never get. 'We'll check your contact list for friends! We won't save your password!' My email password! You wanna install a camera in my room while you're at it?

But some people apparently actually use the service, and thus FB can find out you exist and who you're friends with. They might also mention you etc.
