That of course is ridiculous, because as an advertiser your goal is not to just have people click on your ad. You want people to buy your product or service. A site that forces people to click on your ad because it offers nothing of value or worth is likely to be costing you money.
I know a lot of people here make good money of this deception trail, but I can't see this lasting forever. It is not a dynamic that will be supported for the long-term from many different directions. The people searching don't want it, most of the advertisers don't want and any publisher not doing it doesn't want it.
