They are asking for examples of false positives - a rather public admission that the new algo has problems.
Wow! Take a gander at some of those sites that people are reporting losses for. Go ahead and drill down to the MFA pages. I visited more than a few, all of them would have failed my initial sniff tests. Some of those folks have definitely stretched the limits of AdSense.
If you've got AdSense units and they make up more than 50% of the area above the fold, you probably got whacked, huh? Some of those examples they are discussing at Google have 75-100% AdSense above the fold. Those are what I call click traps for the average surfer.
I'm reading lots of discussions about this and there is a commonality amongst most of the sites that took a hit. It is the number of ad units and the placement thereof when the page is immediately viewed, you know, that above the fold stuff.
I don't see how many of those folks over there at Google could complain, one look at those sites and you can "visibly" see what the challenges are. Who the heck wants to land on a page that has 75-100% ad units filling the viewport? What are these folks thinking? These aren't Content Farms, they're AdSense Farms.
Note: Google hasn't helped this issue any with their incessant emails about placing more ad units, etc. First they promote it - then they demote it. Go figure...
