I won't get into specifics but I'm dealing with the most vile and damaging beast I've ever seen. Various traditional attempts have failed any results.
It's what this article suggests. Your content used by somebody else and Google sets the authority to them and considers your site non existent. This is so bad, that copying parts of your own text, then search within quotes, will fetch the "other guys" site and to see yours, you need to click on that "see ommitted search results" or whatever that paragraph says to show those "duplicate" type pages in the Google results.
This is so nasty and frustrating what can I say. It took months and months to actually realize what happened to my site. It has been eaten alive. It's a massive issue and frankly if I did this to your site or anyone's site, you would likely get cut out of owning your own content. It's far greater an issue than a scrape job. This one eats up your existence. All the tools that Google provides have proven completely futile in my situation. Again, I can't mention who is doing this but I see it with other sites. I've seen the other victims. I hope Google figures this one out but I frankly don't have a phone number to call. This is a biggie.
