In which condition will Facebook authority deactivate the Account of some person?

[curys]

If other email account which is provided to facebook for getting emails and notifications, is deactivated then in such condition will Facebook authority deactivate the facebook Account of that person ? Will all data on the time-line be lost ? Is it possible to regain the deactivated fb account ? How ?

When you deactivate you just sign in and all things are restored

their is an option in the deactivating page which says that you will be back. I you check that option and sign in later everything will be restored , that means your account was temporarily de-activated.But if you click on some other option, your account will be permanently de-activated.

When you send request to lot of unknow people and they reject your request and report it as spam. If this happens more than couple of times, then FB account will be perminantely blocked.

Even if you deactive the mail account, still FB account will work.
