Not sure if these so called coins will be worth anything, but one thing is for sure, this has opened the door for mass email harvesting
I applied, and put in a disposable email for one. Still got my tokens. It was not a fake email, just one I opened up to use for that particular airdrop. I just checked now after seeing this post and have not seen any spam in there. I wonder if there is any use in harvesting ETH addresses, though? They are not really difficult to get since you can see all of the addresses issued tokens on the blockchain though. Maybe you are on to something, we just do not know yet.
