eBit is now sending mails with the spreadsheet of the list of users which will receive the coin. Some people are in the second spreadsheet will just get a little amount. You might all want to check your users there and see if you are on the list. I think are not listed due to a reason that they didnt contribute any ETH. Ain't that a greedy move. 

Are you sure because for me most of the airdrops i have observed needs some deposit for them to give you some free token. It's not that i see all as scams but sometimes it is annoying to invest in some site and it is not being released. I had some tokens that was sold but i still think airdrop is not really a wise strategy to gather tokens and sell them later. For me it is better to buy promising ICO then wait for its release.

GoNetwork looks like its one of the cooler airdrops out there. You have to sign up with an address where you stored ETH. you can get more, if you hae more ETH!

And it is always cool to present a group photo with Vitalik Buterin
