They said that when services are heavily abused to commit crime, they'll act. Phishing doesn't mean heavily abused, it's lightly or moderately abused. Overall, you know, who gets caught, big cartels or small resellers? Small resellers and users, not big boys because big boys are part of the system.
That is irrelevant, because tens of thousands of scammers abuse websites on their own to create light or moderate abuse.
Multiply all that abuse by the number of scammers, and it's an order of magnitude larger than whatever happened at eXch or any single service.
But nobody cares about all that scamming, because it is more rewarding for them to seize individual sites than to take action against scamming as a whole. The most I have ever seen an agency do about phishing is put up a notice warning people not to get phished.
