I am not sure what it is about WAVES but this isn't the first airdrop that I have seen that is "abandoned" immediately after the dev spends time sending out airdrops
As my understanding is now the airdrop indeed will be abandoned. It is just to get attention for 'their' project. It seems however that 'they' don't have the intention to abaondon that project.
I do have a few concerns though.
1) They stay anonymous because they want their project to be decentralized. However decentralization is different from anonymous centralization.
2) Their program does repeatedly alarm my virus scanner for a trojan.
