Someone mentioned about a manual ban. If that was the case why is it happening on one day (July 28) on many sites?
I was mentioning it. It could also be a semi-automatic ban. When looking at this and other threads:
This could be caused by an off-line spam detection spider, quality spider or whatever you want to call it, which spiders suspected sites, checks the site according to internal rules (linking, duplicate content e.a.) and then pushes the BAN button if the site lacks a certain quality level. This is a totally different approach from the current Google SE algorithm which has tunable parameters which influence the position in the SERPS, but not the existence in the index.
