I tried them awhile back.
At the time I had about 4-5k of 404s daily so, per their board whores' requests, inquired about a guaranteed payout (was told if I had more thank 30k per month they'd oblige) and about them building a landing page.
No one ever responded... ICQs, Emails, nothing.
Anyhell, some of the apps seemed pretty nasty - not autoinstalling, but very damn close, so I thought I'd throw some banners up on a hotlinker / scumbag trap I had setup. Checked stats a few days later... nothing. So for fun, I installed Naughty Player (one of their aps) on a box I was planning on reformatting. Besides making an even greater mess of that ole' Dell, the f'n install didn't show on the stats, so I sent another email and ICQs and still heard nothing back.
