Today I placed a very popular keyword into one of my campaigns and put the bid in. 5-10 mins later it was online and I noticed, via StatCounter, that it got 6 clicks from the same IP address very quickly. Each click around 5-10 minutes apart. I didn't expect Google to detect the obvious click fraud but they did! About 2 hours later, the keyword had had 12 clicks - 8 being click fraud. I just recently checked todays stats again and the keyword has now had 4 clicks. Google must have automatically detected the fraud and removed the excess clicks. I've never actually noticed this so quickly (only when running reports), but it's nice to see! Has anybody else noticed this (apart from in reports)?
