At the current rate it's unlikely to be recovered. If you check the other threads in Meta even accounts with signed messages aren't getting restored or at best they have to wait weeks/months. Accounts could be restored by doing a bit of investigation on IPs etc but it's not foolproof and the forum currently doesn't have the manpower to do even that unfortunately.

On the new forum at least there will be multiple 2FA options to secure your account but I know that doesn't help you right now.
