well, they are already listed in quite a few exchanges and I think they did not get enouch feedback from traders, this is why they organize a new airdrop. I doubt that this will success.
It got listed on poor exchanges, I can't find this Token on Coincapmarket and I don't think traders buy any token before check it on Coincapmarket. Airdrop only increase sell orders, but it's good to get more followers on social media.
