You guys really fucked up this airdrop marketing wise. Not enough information on specifically the fact that you needed an alias expiring after May 2019. I've been in syscoin got a very long time and thought I was all prepared to get the drop, my main aliases were set to expire shortly before May.
Serious fuck up. Go check the syscoin slack and see the shitstorm you guys created.
The information was on the website and the minimum expiration time was requested by the Syscoin dev team.
