I don’t think this is possible in the first place. Someone will always be able to go around the system entirely and give someone their entire account. If somone wishes to sell all their names at the same time (or make one account per domain so they can sell it), there’s little to prevent that. I think making it harder is probably more trouble than it is worth for most malicious actors though (especially as they have to work with each individual account to retain the domains).

As to consensus mechanism, I have no idea. I don’t have enough experience with such systems to say one way or another.
