the most fair distribution for limited sought-after resources that are inconsequential (like domain names) are raffles. let people apply in a 4-week window and then randomly assign it to one of the applicants.

then don't allow reselling, just allow giving it back and do a raffle again

how about make it round-robin, so all 10k of them get a fair slice of traffic? ;)

first served or random from a waitlist are other options.
