September Penguin Webspam Update - Is A Major De-Indexing Imminent?

Thanks to all the SEO rat-finks stepping into Google's confessional booth over the past few months since the April Penguin webspam update - http://www.onlywire.com/r/100902110 - I suspect a few hundred thousand backlink sites are going to feel the wrath of Google  - and soon. After all, the Holiday shopping season is coming soon and gray and black hatters musn't spoil the profit potential of all the big retailers and Brands who now dominate Page 1 SERPS. What better way than to totally de-index all those horrible, horrible domains that were propping up a site's authority and PageRank?

If you thought the ROI of link building sucked before - just wait till the axe falls with the next iteration of the Penguin update.
