By their site I think two things are clear Islandmaan.
1. They are most likely fraudulent CPA webmasters, I wont call them affiliates because that implies a mutually beneficial partnership. Net Revenue affiliates would NEVER advise players to play the bare minimum to collect a bonus and then move on to the next victim casino.
2. They will mostly turn up here (if they havent already) and piss and moan that the casinos they are trying to rip off wont pay them!
Take a look at their pitch:
Welcome to CasinoExploit.com – I designed this site after milking online casinos for almost $20,000. Following the guidelines on this site will enable you to take advantage of a loophole in casino promotions, and earn thousands of dollars in just a few weeks. Here’s how:
1. Choose a casino offering a free sign-up bonus. (e.g. $100 free for $100 deposit)
2. Play perfect blackjack as described on this site, reducing the house advantage to less than 0.5%
3. Play the minimum number of required hands.
4. On average you will be down 0.5% – next to nothing!
5. The cash bonus is now pure profit, move on to the next casino!

Like you said, its a damn shame dont put the same effort into honestly promoting casinos and EARNING a nice monthly commission.
