I would like to ask on how do you stop an adsense attack on your blog? I just checked my stats and I see that there are a lot of invalid clicks. I will disable adsense for the time being.
There was a program that used to stop invalid clicks from the same IP. Search around in the forums, I think it was called Ad logger?
What is an invalid click? Invalid clicks are clicks generated through prohibited methods. These prohibited methods include but are not limited to: repeated manual clicks, or the use of robots, automated clicking tools, or other deceptive software. Please note that clicking on your own ads for any reason is prohibited, to avoid potential inflation of advertiser costs. All clicks must be generated as the result of a user clicking on the ads. We therefore require that Web pages do not include incentives of any kind for users to click on ads. This includes encouraging users to click on the ads or to visit the advertisers' sites as well as labeling the ads with text other than "sponsored links" or "advertisements." Google Adsense Help
