I just ran this on my tgp's and found over 80 redirect galleries.

Of course, as a bonus of checking some of those galleries I got some great spyware that i'll be spending the rest of the day removing.
With that tool you can get a list of all the domains that are known as cheaters. Unfortunately the list is over 5000 lines. I put the list in a text file so you guys can download it. You may want to check if you are in there. Personally I just composed a while loop that inserted it into all my TGP blacklists.
