I disagree.. I was one simply promoting a hide ip software and finally got my ctr above 5%, and got each click down to 3 cents per click. I started getting a great ROI, then adwords banned my account with no notice, and when i asked why, they just gave me their TOS link, "we have the right to refuse service to anyone". Hide Ip software wasnt even on their banned sites, and i saw other people with it. I think i just figured out how to get a great ctr and my cpc down drastically. And they decided to punk me for it.
