I know about something like airdrop. It's a promo campaign of MyWish project

You receive a promo code from this link http://docs.google.com/forms/d/1q1uLDPO3urwGirr5_netu-_Qd45X5hnkgcJVWQqjLec/viewform?edit_requested=trueHere
Then you should share it everywhere you can. When some people will deploy a crowdsale contract through your promo code you'll earn 0,2 ETH from every contract made through your promo code
