I am going to block them via robots.txt file as a test. I will let you know the results once the links are removed. I do know since seeing them 95% of all our traffic has been gone so its worth a try. Will post results if i see any.
Note: i just found this..

Apparently they have malaware and trojans and all kinds of goodies. SOme say this site is not affecting rankings but it certainly does no good.
I have blocked them now – see what happens.
