Let's say that you delete completely a facebook account to create a new one. You delete the email address you used to register in the site and you use another one. If you use the email you used to register in the new account will facebook remember it or it's removed completely? In general are the information of the account connected with the email address? E.g. I have heard that if you sent many unanswered friend requests facebook stops you from sending other friend requests for a while. So if let's say that happens and the user removes his email address and uses it to a new account will the new account with the old email address remember these information and maybe get a message? I give it as an example because i was wondering if facebook connects what happens in your account with the email you use and keeps a history even if we don't know it? It hasn't happened ever to me . I just use it as an example to better explain my question.
