You weren't receiving email before because your email got banned/disabled, and now you'll still not be receiving email. Nothing is lost. The forum account isn't banned or anything.
I want to get a clear scenario from you theymos, if email is been ban or got disabled and the user of the bitcointalk account have not noticed for long period that his email is not in function and a hacker has penetrate to his bitcointalk account and succeeded hacking the user account, can the person retrieve it's account through the management of the forum while it has not sign a message with its receiving address of the first earn for the forum??
You will have to provide some proof of ownership for the community to be sure that you're the real owner of the account. A signed message from a staked address or an previously used address in campaign or business is the popular method of proving ownership AFAIK, without that, it will be difficult for you to get your account back. Though the community may look into the matter, and notice if the account has changed hands, a neutral that will certainly be given in that regard. But I doubt you can gain access to the account just because you claim you are the legitimate owner.
