@virtrualreality - I am seeing the very same thing in AWSTATS. Sites with names like prostitutki-xxxxx.org and many multiple of the same. Also a science news site that is under literally hundreds of different domains names with all the same content. I ran back my search and it appears this started a little over a year ago, slowly, just like my decline. It's clearly a negative seo campaign, and from what I'm seeing it's not targeted to just a few sites, it seems ANY site can be affected. The older the domain, the worse the problem seems to be. I think if everyone takes a look at their server logs rather than what G reports, they will see similar "bad links".
The widely reported precipitous fall of many sites here might be an indication that this weighs heavier than once thought. That or the algo is still broken...or both.
I personally don't buy that they disregard these links. Like everything else in WMT, they are slow on reporting them, but the algo must be taking them into account. I just don't trust what they do or say anymore. You are free to think otherwise.
The good news is that I'm seeing Bing closing in quickly on Google. G used to be 95% of my traffic, Now, with only marginally smaller volume, Google is less than 50%. Hopefully the pendulum has begun to swing.
