Nonsensical adless MFA pages

not an oxymoron

[loudspeaker]

A few months ago I started noticing a new brand of sites popping up in my ad units - a site with a totally nonsensical page and... no ads. Nothing is even clickable on the page.

The text on the page goes something like (I am paraphrasing) "Making shopping decisions is difficult, especially if you're making them online. We are here to help you find the best deals". And so on and so forth, about 3-4 paragraphs. Like I said, no links.

I can't really explain this phenomenon but it was widespread enough for me to necessitate multiple purges with perhaps a couple of dozen of domains.

I was very puzzled and I wonder if other people saw the same thing. What do you think it could be? Was it:

a) Some spyware page that perhaps attacked though an IE vulnerability?
b) Somebody just trying to measure traffic that they can get through certain keywords on AdWords?
c) Somebody just trying to set a cookie on people's computer, for one reasons or another?

Would like to hear your opinions

d) Someone who was banned almost immediately and hadn't noticed, so they were paying for traffic but the ads had disappeared?

e) Someone playing the quality score buying cheap clicks till their PPC is at bottom lowest then later on monetizing the traffic with Affiliate links
f) Someone hiding their monetization ads for any traffic not coming from an AdSense click in the referrer

Ha! Haven't thought of that. Sort of clever, but I still don't get why they'd want to do it.
