Yup the old is being removed.
What accounts are you trying to recover?
Is it not possible to recover accounts then if the email isn't yours? And just an old account but I can't remember the email on it.
Yes, it's still possible.

Enter the log in information of the account, and proceed. The second page will ask you if you have access to the registered email on the account, choose no. The account recovery form will load.
