They have two sections: "Daily Aidrops" (trusted airdrop) and "Untrusted airdrops" (potential scams).. They are posting also on their twitter page https://twitter.com/airdropaddict
But on another side, some airdrops are worth to join. I made in November over 3 ETH just with two airdrops: EGOLD and BLUE (i had kept about 50% of both )
I believe, that some of these coins http://airdropaddict.com/, will be worth some $$ in next few months.. We will see...
