Set the mail address to <something>@example.com (making password recovery impossible) and then set the password to some long random string that you forget afterwards (making login impossible). This will cut you off from the accounts.
Real deletion of the accounts isn't possible for legal (in case you bought anything they'll have to retain that information for tax purposes) and technical (forum software referencing the account) reasons.
