I remember my account login and password, but I can't login

I remember my account login and password, but I can't login because I no longer have access to my old email. login page ask me for some "authentication key" from my old email.

acc. name Wander1ust.
I remember the acc password.
I'm not quite sure if I remember the old email. Maybe it was disposal one, if it was google one, I can tell for sure. But I would rather not write it here in public.
I donated once about a two years ago, about 30 bucks.

Please tell me, if you need any additional information to help me restore the access to my account.

P.s. This account is new one, just to create this ticket. And I can't make "ban appeal" here, because I have no bans on this account
