OK I guess what you were asking was what personal information do you need to provide to become a moderator.
All you would need provide was contact details to where to send the login for a moderator account.
Alternatively I could open account creation and give users delete/ban privs based on tripfagging.
An admin with total power over the board could be appointed the same way.
I would still own the server so it would be impossible for me to make it impossible for myself to regain control as long as I'm the one paying for it.
I could provide the data to a tech savvy anon with a server of her own to perform a migration to, or I could do it myself with temporary access to another server. That access can be revoked later, especially if 2FA is enabled afterward. Anon doesn't need to provide me any personal information to do this except a paypal address if she wants to take up the offer the costs of the first month's hosting.
If anon was hosting this on her own server I wouldn't be able to alter any of the content being hosted (any more than any other poster), but I would still have the power to redirect the domain to another server.
I haven't done a domain transfer before, I'll have to look it up, but you are legally required to provide your name and address to your DNS provider who is in turn required to make the data unavailable to 3rd parties (my other domain was registered before this became law). I'm not sure if my knowing anyone's real name is a necessary part of the process but it might be possible to broker an anonymous sale of the domain for a nominal amount which I can then repay.
