I ran my first adwords campaign through a coupon that I received in my gmail. It was for $150 credit for $150 spend. After finishing that spent. In the meantime, another of my gmail account received another coupon code through Google if I started a new adwords account. I paused the campaign on my original account after the credit was redeemed. Then I started another adwords account, applied a bought coupon through ebay ($75 after $25 spent) and made a similar campaign promoting the same website. I was wondering if I keep buying coupons and creating new adwords account, but promoting the same website, will I eventually get banned? I have used different credit cards but billing name and address is the same. Will it matter if the billing name or address is different (a friend's) for a new account but again promoting the same website with similar keywords. Does Google monitor this and has anyone site been banned by continuously making new adwords account and applying coupon codes to run the ads for the same website?
