Get it right, since the forum respect for your privacy, they don't very the email address you used at the point of registration, however, when your account got comprised, then you may need the usefulness of the same email to recover it, i will advise that you should use your own personal email and also go to your profile under forum information and edited it by checking on the button that allows your email hidden to the public, using a fake email may cost you now or later, but you can always create an email address for that as well if the address is not taken already.
