I don't like this at all - as has been said before, are Google seriously going to pay publishers the same as if a "tickets", "football boots" or "weight loss program" ad was paying for clickthroughs (all are examples that I have seen in the past 24 hours). Like hell they are. Most publishers probably won't even see the ads - but they may see a drop off in epc/cpm rates as consumer see this rubbish.
Or maybe it's user-targetting for all Adsense publishers?
BTW - is this Image only ads? i.e. is there also a text versiopn people have seen?
Can anyopne supply a list of all the google variants so we can block them? I have already done .com and .co.uk but have seen a few ads still coming through with google.nl as someone else noted above.
One more step of G pushing their own interests first.
