You can pretty much have a video call with me. Check my id and I can explain you how I derive upon my username. You have blocked me from accessing my own account when there is no fault of mine. That's very wrong. You have made hacker look good and me look bad whereas I am the victim here.
The forum did not block you out arbitrarily, it was done to secure users who may be dealing with your account which was compromised. And the series of time it has been compromised has made it difficult to determine who's behind the keyboard at this point.
I'll suggest you message the cryptios member and suggest another means of recovering your account, as it seems they do not trust you still control the email or private keys linked to it at this point and they will not want to give the account over to a hacker. Although, I don't see how successful that will be.
