I've checked blockexplorer and it seems there is no airdrop for me. I dodn't know why (I can only guess). It's the most unfair airdrop ever seen, but what could I expected of Monero scam members.
It seems they removed users also after airdrop end(even with a confirmation id) automatically without notify them or asking for more details.
https://forum.decred.org/threads/airdrop-rundown.313/Checks were also included to investigate similarity in IP addresses and e-mail addresses across entries - this process was performed manually as well. Whilst no evaluation system is perfect, every reasonable effort was made to pay each applicant as much time as possible and balance these responsibilities against the demands of software development and testing with as few delays as possible.
However, in response to community concern, and as a show of good faith, the project has decided to conduct another (and final) sweep of the database to check its integrity and remove problematic entrants that are identified as fraudulent. The outcome of this may result in each successful participant receiving slightly more coins than stated - but no less than 258.93958076.
Most likely case in IP addresses (no one knows how many claimants were per your public IP) or just simply bad luck.
