first served or random from a waitlist are other options.

First come first served is capitalism in disguise. Someone will automate a tool that watches for these and jumps on them, and the person with the most resources, can get a close network connection, etc will "buy" it.

Same with waitlists.

It's impossible to avoid capitalism!

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? ;)
