I am running many small sites that earn 2-3 dollars in average per site.I provide free printable graphics for different occasions so I have small niche sites for every occasion. In last month which was February 2014, my revenue fluctuated a lot like at one time the earning shown was 32$ and the next minutes it was dropped to 13$ and next moment it was 5$ but at the end of the month everything got adjusted.
Yesterday I noticed a weird thing that upon my site that earns most, within 15 minutes the CTR reaches to 180% and the earning was 170$ + from that site, I reported it to google immediately using that form that they provide to report invalid clicks, I got no response. After that I tried to trace an IP that was constantly present on my site and blocked it. CTR kept on increasing so I immediately removed all the ads but the revenue still started increasing. After that I removed that site from the list of Authorised sites. Soon after that, same thing started happening to another of my websites and I finally removed all my sites from the list of authorized sites. It's been around 16 hours now and google is still showing that 200$ + earning and hasn't changed it at all. Neither it has started showing that message that your ads are appearing on the sites that you have not authorized. .. that usually appears. What should I do? When should I open my sites again? Will google ban my account if same thing happened again?
