Adsense Fake Clicks
makecheck: You might be able to obfuscate things a little on your end, if you can change the source code used to generate your ads.For example, the bot is probably searching the page for links matching specific URLs, but it might be fooled by selective use of URL encoding.  Say, if you replaced the letter "o" with %6f in your ad hrefs, the links should still work, but they'd no longer match in a simple text search.
