You see great financial potential in this project long term? Airdrops themselves are worthless - that's why they are given away. You want to start a community where people can register to get airdrops? How will you make money - a subscription?
To me, this sounds like, their users will have to pay a subscription in order to later register through them for airdrops as referrals. 
Two solid airdrops per year do not mean that this branch is developing or that it is particularly promising.
