It's happened to me also Skuba. One of my sites has 200k+ pages and over 4K backlinks. It's bad enough that G only shows less than 250 backlinks right now, but the vast majority of the pages (90%+) have gone missing. On April 2 our daily traffic dropped from an average of 30K visitors per day to next to nothing. We have no connection at all to Amazon, so I suspect that it is in fact a filter that demands a certain level of difference between pages or else it blows them away.
