Hacked Facebook Account And Changed Email. Friend requests have been sent to people you don't know. When a new address is added to an account, you should get an email at the old address.
Looking into the scenario of your account getting hacked,you must use a password manager software like lastpass and allow it to generate and save strong passwords,so that it'll release any burden for remembering it and your account would remain secure. Please help me to recover it. Messages have been sent that you didn't write.
