@Nano Aren't those links like the kind provided by those contextual link providers like kontera, infolinks, vibrant media?

Those are used by a LOT of sites, way more than the 12% affected by Panda.

On their own I doubt they're a problem. Maybe combined with all the other stuff, some small influence though.
