While this might be true a percentage even maybe a majority of the time, in my experience they don't just send money back to you. I had google's adwords people tell me it's not certainly click fraud, there are all kinds of possibilities where actually different people are clicking on the ad like if an article goes viral lots of people could be clicking over from there.. These were clicks I knew well, as we ran groups of ads from several businesses in the areas that all did the same thing. I knew by the pattern, there was no way 200 people from 8a -9a clicked over to this business's ad, and could also tell by the lack of calls / appointments. The real kicker was these ads are limited to only show basically along a 5 mile path of highway, very few rooftops in that area - as to get mobile searchers on that side of town - so they were convinced hundreds of people driving down the highway had all clicked over for info and no appointments while driving. They said no proof, no refund, have a nice day.
