I like how Uniswap conducted the UNI airdrop. They implemented the airdrop contracts silently. Because if they had announced it priority to the distribution, thousands if not millions of people would have registered. Congratulations to everyone who benefited from the airdrop. I've used uniswap before but it was earlier this month so I wasn't eligible to participate and claim.
For sure they were trying to not let everyone know about it, because every other one would register 10+ accounts just to get "free money" which are originally intended for real community members
