I am with 70+ networks. Oflate, I started a blackhat method. Posted in my last thread in CPA section. Now the problem is - all was well with every network, now all of a sudden, a good network raised their eyebrow. The stats look like this 100 clicks 49 conversions. They have no clue how I have done it, coz I covered my tracks etc. But may be they are smelling something. Please shoot me your suggestion guys.
