I have a longer post at my blog at http://www.nathanmalone.com/blog/archives/3/ , but basically, try searching for info:http://www.digitalpoint.com/tools/ad-network/ on Google, and see what you get... I would use the link above, as not all datacenters are displaying this data. Whether this is related to the discussion in the Co-op forum about Google deindexing sites is up for discussion... Please help me by digging this story!
Ahh yes, proxy trash strikes again. This has been going on for some time... Google sometimes penalizes the wrong site when it finds duplicate content.
Well, it seems that they have fixed the problem, as it is not occuring anymore on any datacenter that I checked. However, I have screenshots of it.
