That's not a good idea!
Google's Ad Sense checks where the ads really appear on the page, and 
calculates the rank (= money!) from this info.
If you reject the checker you will get no profit from AdSense at all.

rejected the main googlebot is also not a good idea.
The googlebot is a good thing.
You just have to prepare for being "slashdotted" to death once in a 
while. Some referrer check or referrer throttling.
