Ads appearing on sites collecting PPC payments have a serious problem with fake clicks, from exchanges, robots and some Paid To Click and microtask sites, the top ad networks like Google have sophisticated click fraud detection, and have lower fake click rates than the 2nd tier networks.
Google search ads are less prone to fraud, though I believe they include search boxes on individual sites as well as Google.
Some ad networks place ads on premium sites that are much likely to generate fraudulent clicks, though clicks on something WebMD are not cheap.
I have reported to Google several Answers spammers directing people to click on Adsense ads on their sites, with little effect.
Of course there are. If advertisers don't generate results from their advertising, then ad networks will cease to exist.
Of course, not all web visitors will click on ads; they are there for the information on the site itself in the first place.
Having said that, if the ads aren't blatant and are, more importantly, relevant to what the visitor is searching for on that site, then clicking on the ad to find out more is a natural response for some.
