Now here is a classic click fraud symptom. This user at 172.24.6.31 used a proxy server at a Level3 site 184.108.40.206 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.

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.
