EDIT: Lol Dalton's PART of YC now. Hey dude, why not pitch it then
I don't even know if it solved bots. Rich countries, rich organizations, rich people could do a lot. $100M would buy you 10M bots.
I think the idea is that it shifts the incentives. Sure, a rich nation state could buy tons of bot accounts at $10 a pop. But is that still the most rational path to their goal? Probably not, because there are lots of other things you can do for $100M.
