Cool idea, I don't understand who say this is scam.
- They don't want any ETH to launch the product.
- They have a product in alpha stage under development
- They stated and demonstrated what the purpose of airdrop race
Who don't want to participate simply go off from this post and avoid writing "scam scam" like monkeys just to raise the activity level, otherwise write your doubts and wait for an answer.
Good luck to the developer!
Race!
