Has anyone had any difficulty with Google Adsense?

hi everyone, i was involved with an automated pilot system that involved posting ads on Google AdSense. I spent 2 months advertising and only made $50. But what i found out one day that my minimum bids at 9pm on a Friday were set between $.25 to $1.00 max, i was getting great clicks, impressions and high CTR(Click Through Rate) until 1am the next morning i looked and all my keywords jumped to $12.00 minimum bid. I couldn´t believe it. I contact Google and they gave me the run around. I find it hard to believe that it jumped so much. I think they new i was using a system. I did some digging with some insiders and legal team, that I cannot reveal here but very impressed with Googles Marketing Campaigns and Advertising guidelines that you can actually get around, but i did not bother.

1) has anyone experienced this before? If so, please share
2) Also, i am now involved in another great system that has proven so far very effective, has anyone experienced great results with funding proposals(your profits put back into advertising and marketing)

Hope to hear from you soon and feel free to visit my site below..I am excited about it!!!!

Thanks

Brian
