Ask HN: Domain Lost – GitHub Email No Access

I created this throwaway because I am ashamed of my stupidity. But also because i don't want people to know, which account to try to get in.

But here it is: I have been in a bad phase in my life. I was financially ruined and didn't see that my domains were cancelled. So I missed the grace period. Someone else got ahold of the domains (unused, cant find out how to contact the person).

I need access to my github account linked to that domain. I have important repos there. But after logging in, github sent a confirmation mail to the mail address i cant access anymore.

I hope the person is no dev. Also I really hope there is no catchall mail for that domain...

I need ideas on what to do now. Github does not seem to have any contact mail that would be helpful to me. And even if, I guess, they would not remove that email by a strangers request.

But I could prove i was the owner of the domain for many years - also when the github account was created with that mail address...

Any ideas?
