Phnatom didn't airdrop anything yet, they just went silent so I'm not so sure that we'll see it any day. Founders had problems with the SEC after all (do you know Centra? They are the same guys)
They haven't launched their mainnet yet so it's currently impossible to receive anything. They build on Ark v2 tech which was recently released and I'm sure they have to adapt some things, this may take some time.
I don't expect anything, but I would say "thank you" for these free coins.
