You already know the point before making any investment, wich does some proper research, if you want to participate in ICO you should do more research from team background to that token it self. And yeah you can make some bucks by doing airdrop, but it's not that much money cause you just do some simple task like following twitter and filling a form after that. If you want to make more money I suggesting you do some bounty campaign, of course, if you to join signature campaign you'll need a better rank, but as a newbie you can participate in facebook, twitter, LinkedIn and many more, I guarantee that you will earn money quickly by doing bounty instead of joining airdrop
edit:
ah if you refer to that specific airdrop i have no idea cause there no official thread about that here. And just want to tell you that there plenty airdrop here, if you want to join bunch of them, is ok, its only take your time :3
