Instead of targetting individual link sellers, google is targetting ad networks which are selling ads on behalf of the online publishers
One major ad network was marked as having malware and it has greatly reduced revenues for the ad network. All browsers like Firefox are giving the error.
Usually at least 10-15 new ads are sold every month, however in July 2018, not a single ad has been sold after google flagged the website of the ad network as having malware.
