This is why a lot of subscription websites (which this was, apparently), don't display ads to logged in users. A small dedicated audience looks like click-fraud. Adsense and the like is best for drive-by visitors. I did that even with my own websites, even though there is no subscription fee. Logged-in users get no ads, because I don't want them to click on them. There was a similar issue on HN a long time ago (years?), but I can never find past articles that I'm looking for.
