Sry didnt read the thread fully, but giving my answer still.
I think its a clear case of scamming for free marketing. They are trying to get people see the coin and make it "legitimate". Then they list it on a exchange as fast as possible and hope people dont have a negative view of them and sell the tokens.
The "airdrop" itself is something like " GET HUGE REWARDS UP TO 100$ BOUNTY BIG AIRDROP ". Then they want people to spam it everywhere so that if even a fraction of people buy into it after listing, they get free money and try to exit with as much money as possible. Maybe some people sell their tokens off, but still the devs might dump much more, or even worse they themself fill most of the people in the airdrop. So essentially they drop most of the tokens to themselves and then say that they keep only 5%.
