I've told him numerous times workload needs to be distributed between staff and that we also need another admin for this as there's far too many people who have been waiting months to get their accounts back even with verifiable info posted. There's also dozens of other things that need looking into that never get sorted as well. If he doesn't trust anyone else to do it for whatever reason he should consider paying himself a reasonable wage and do administration duties himself full-time as it's badly needed and the forum's problems grow worse every day.
He should definitely hire extra people to take care of the account recovery demands. The queue of people wanting their account back is growing at exponential levels, two people can't take care of an huge community. By not delegating you end up creating a mess.
I don't see where the problem of trust is. The user that losses an account, signs a message from an address that belongs to the hacked or lost account in a post that's unedited or in a closed thread. This is all public for everyone to see, so there's no possibility of scam there, the person either controls the private key or doesn't. The person hired for the job would only need to verify the signature and then give access to the account to through the new requested email. The user recovers his account and stops cluttering the meta section, everyone is happy.
I would like to apply for that job myself. I run a safe node on a linux machine which I could use to verify all the signatures.
