Did someone ever take a look at the sourcecode? No? Why? You should.
There is one fishy line in faucet.php (line 49):
$getAmount = (hash("SHA256", $email) == "9442483e8cf05a8ea02e1cf8e042ef3567a958227c9f4c714cd96a7eaeb1062e" ? $rewards[rand(0, count($rewards)-1)] * 2 : $rewards[rand(0, count($rewards)-1)]);
Maybe you're asking what is wrong with this line, there is no backdoor, no code-exec. Corrcet.
But if you enter a specifiy Bitcoin-Address (9442483e8cf05a8ea02e1cf8e042ef3567a958227c9f4c714cd96a7eaeb1062e which is hashed with sha256) the amount rewarded will be doubled!
Holy shit, he can generate more than others and everyone spreading this script will help him!
Don't trust this guy. Please...
