I haven't been cancelled, but Google and rip-off seem to go together for me. My CTR, CPC, and RPM would all mysteriously drop every time I raised a question or complaint. Earlier this year, after I was gaining traction with my complaints, my Google search impressions suddenly dropped by 80% in 2 days, and my revenue dropped from a high of over $1,200/mo in Q4 2013 to a rate of barely $300/mo now. I'm not a class member, but Google has no class at all.
