Many of us do some form of cloaking, often there is simply no other way. For instance I cloak the text ads on my site to stop Google from running impression counter or from crawling them. They're there for the content, not the ads, the ads are for the visitors.

Is that adsense ads you're talking about? don't they know themselves how many impressions they send?
If its other text ads - what type of impression counter can they run on YOUR site?
