i'm a huge AW fan willing to bear some fraud clicks; google can't police the beat to perfection; fyi my spend is USD $50-80 daily. recently 4 days of many fraud clicks, i knew who it was (easy in a small market), i called the perp and persuaded him to STOP. silmultaneously emailed google, gave them the perp's url and precise fraud click periods: they responded ...no evidence, natural spikes in CTR (balooned from 2.5% normal to nearly 20% for KW). any advice out there?
