Any small range of IPs that persistently came up would be pretty obvious I'd guess. With 200,000 unique IP addresses every month a handful generating most adverts would stick out like a sore thumb.
And it's not hard to write the detection logic behind this, when I made the detection system for all of Premium TV's football websites it took less than a day to work out how to flag up accounts which had their usernames and passwords shared on forums, based on the distribution of IP addresses.
If I can do that in a day with little significant financial incentive, then Google can do a much better when their entire business model is based on adverts.
So yeah... it's not worth it. A small revenue is better than no revenue, so no-one should be clicking adverts thinking they're helping out... either click an advert because it's something you're interested in, or don't... anything else is likely to hurt us.
