It fails to mention that Github and HN accounts must be older than January 1, 2017. This is what I saw in the app when I tried to join the airdrop: https://i.imgur.com/ZOZ1rB7.png
I hope that's an accidental omission and not an intentional dark pattern.
Not a dark pattern, an accidental leftover string from our testing. Any account registered before today qualifies. I'll deploy a fix to that shortly. Update: deployed, although you may need to restart your app to update the text.
Sucks you had the sign up date prior to the announcement. When I read the announcement I immediately signed up for a keybase, HN and Github account and then find out I cant be included because I signed up on 9/9/2019. You would think that would be the incentive to at least give a little buffer for people to join in that were not aware.
I hope that's an accidental omission and not an intentional dark pattern.
