There are companies outside USA whose sole purpose is to defraud the search engines at your expense. They do this by creating sites which feature paid search engine ads, and then sending fraud traffic via virus or otherwise and getting paid for the click. While search engines try to catch as many of these sites as possible, these guys have become really smart over time. I have seen these fraudster companies filling in forms on website just to fool search engines to thinking its a legitimate click. A good SEM practice is to first catch the websites that are sending you false clicks, and then as a second step good measure, evaluating each website for the quality of traffic it is sending your way. When each click can cost as much as $5 to $10, its an easy way for scammers to make fast money. While search engines like Google are doing their best, they too are not very incentivised to fix the problem. Why? It is because fraud click or not, they get a cut of the cost to you.
