I used 10K hits and the none paid version gave me a multitude of traffic, but it was all direct annon traffic. I upgraded to organic google, but there version has no key words, which would look suspicious.
Sometimes 10K showed up, even though I specifically said NO to any direct traffic and only used referrers and organic. Hitleap was the same and EasyHits4U showed up that it came from EasyHits4U. As did TrafficAdbar and I would say if I can see it then google with all their technology defiantly can.
The only way I can see is to build up a full market research and target through social media and other means, including word of mouth. Any bots will be detected and you will be banned.
I also would take adsense off the front page and drive traffic paid or not to the front page in the hope it will convert to subsequent pages.
