Here's a list of the sites that they have link codes for, but are now redirecting:
Assault My Ass
Chubby Chicas (actually,
that one is 404)
Cock Strokin Sluts
Cream Filled Cuties
Dildo Sensations
Girls Gone Black
I Crave Sex
Jizz Dolls
Mother Humpin
Put It In Your Mouth
Real Dirty Videos
Watch Me Suck Dick
We Love Booty
And it's not like I put up the links without looking - I do actually take a look to make sure everything is legit. The last time I added one of their sites was the end of October 2008, so sometime in the last 3 months they started to redirect, even though there's nothing about this in their admin/news.
