Ask HN: Do you ever show appreciation to a site by clicking on Google Ads?

I've been thinking about the merits of this type of action. It seems that in engaging in this type of behaviour you're diverting a portion of someones Adwords expenses to someone elses Adsense earnings with Google taking a nice sized cut. It seems unfair to the person running the Adwords campaign. But it does seem like the simplest way to quickly acknowledge someones work by sending them some Adsense revenue (even though it's peanuts). Any thoughts on this type of behaviour?
