Four keyphrases, four ads clicked within 34 seconds

Now here is a classic click fraud symptom. This user at 172.24.6.31 used a proxy server at a Level3 site 65.57.245.11 in San Francisco to find four of our ads and click them within seconds.

Update: The "cuplrit" was Google. Apparently the Adwords people use this IP address when checking your ads. :) The official answer from Google about these clicks was some boilerplate answer which said how wonderful their system is, but nothing specific.

The Chattanooga Click Click

This Bellsouth user in Chattanooga, TN, just loves to click - 11 times, no less. He didn't buy any calendars after all that. Google only charged me one click, which could have been for someone else.

Another shed-loving AOL clicker

I am seeing such click behaviour daily and cannot make up my mind whether this is fraud or a novice web user. Unless I were to see someone clicking an ad several times to return to an advertiser's site, I won't be able to ask them why they do that.
