It is totally screwing up my web stats. I have no idea how many people are really visiting my site now. I agree that it would be nice for Google to get more involved with this. I think they actually have because looking at my AdSense stats now, they are automatically not paying me for any clicks when the user goes to mysite.com without the www at the front. Remember before I said that a lot of the bots were not using the www at the beginning of the domain.
It is interesting to see that AdSense is blocking that revenue now, instead of later when they do the final month payout. But I still wonder if they are blocking valid clicks, I still think my revenue is lower than it should, and unfortunately I have no idea if my traffic is down this month since I don't have a clue of how many visitors I really have on my site.
I am just thankful that the bots have never went past 10k a day for me. If they do get as high as 60k like other people I am blocking IE9 for sure.
