You can create a new account with a valid email. From what I understand it is very difficult to prove than an account is/was yours if you don't have access to it any longer.
Much respect, Thank you for the response.
You're welcome. I'm not MediaWiki staff... just a user who reads the help desk often, so I can only give you my understanding of it. From what I've understand and read to date the reason seems to be that it's not about providing ID, its about proving who was using the account prior. There was no ID associated with that account, the only thing associated with it was an email. So pretty tough to match that against anything except the email. How would they go about proving that it was you who created and previously accessed that account? Look at the IP logs? IPS can be spoofed. ISP records? --Those might be tough to get. So I think they fall back to expecting you to have access to the email the account was associated to. Aside from that it's really tough to prove who accessed the account previously.
