After Google has obviously declared war on link networks, what's your strategy? If you have been using one, did you cancel your subscription? Move to another provider which was not hit?
It seems obvious Google has manually inserted spies to some of the networks and blacklisted the domains they found to be used by them. Most of the networks have already (or will do so later I guess) reacted in a way that subscribers do not even get to see where their links are, so as a subscriber you won't know what you get for your money.
