No to throw salt on an open wound, but has anyone at WebmasterWorld checked the author for veracity? This seems like an out-of-the-blue occurrence that happens to JUST ONE PUBLISHER, and all of a sudden it's front page news.
As a journalist, my first duty is to confirm that the condition actually exists as the OP says it does. I'd also try to contact Google's Adsense team before putting this on the front page.
Seems phishy to me.
