Get this

Some loser who thinks he can cheat adsense is going onto craigslist onto every section they can in the erotic areas and posting the following

a link to a supposed escort review site called bonethis . com

Upon arriving at the site you see some rubbish about the site not working in internet explorer and needing to download firefox for it to work (even if ur using firefox u get this message) and they tell you to download picassa if your getting the error stil so they are duping you into downloading two products they are earning referrals from and it will do you no good

Then they proceed to show you a firefox adsense link of which they hope everyone visiting will be dumb enough to click and download firefox trying to icnrease their referrals in google adsense

I cant beleive people can get away with blatent click fraud like this totally going against the adsense rules and scamming not only google but the people who come looking for a site that doesnt even really exist

Its pathetic lol

That's indeed pretty sad, but unfortunately part of the reality. The good news is that the Google engineers adapt their algorithms (both on AdSense, AdWords,and the main SERPs) to provide a quick death to these short-lived schemes.

If you value your AdSense account, be it for CPA/CPC or CPM revenue, from either their classic ads - or referrals - I would not resort to switch and bait black hat techniques.

Google is (as of today) a $173B company.. they can afford a few techniques to counter these clowns.
