The Incident Response Lead, Google Security Team replied that "We’ve investigated your claim. At this point, all we can verify is that our automated systems terminated your accounts, as a result of your trying to inflate the clicks. This is exactly how the system is supposed to work."

ionut!

they replied only after the person himself has notified them! until then they doesnt know about the incident!

He said: "our *automated* systems terminated your accounts".

Anyway, no system is perfect and I'm sure there are many ways to fool AdSense's click fraud detection.

Thank you Sankar :)

I don't understand this phrase: "This is exactly how the system is supposed to work." That is to say: if I can fraud AdSense, even if they detect it, they will do absolutely nothing, except closing the account after some days/weeks? Strange.

TOMHTML

the famous DIGIT magazine has tested the script of the guy and contacted Google!

TOMHTML

if u want to try that hack please try in a dump adsense account or a useless account dont take risks in u r account!

So, if they didn't contacted Google, the magazine (& the guy) should had win big money or they account would had been terminated anyway?
In other words: Has Google detected the fraud before Digit magazine contacted them?

Nope! Google didnt unless they informed google!
