One of the emerging clarities about Panda seems to be that you've got to been seen as the original author of your own content to avoid demotion.
So how would Google go about doing that?
I confronted my biggest scraper competitor regarding sales copy he stole and several other copied aspects of my site and I used the Alexa Wayback Machine as my evidence. The next day the scraper blocked Alexa's Archiver robot, erasing all that past data that was quite damning to his case.
Does Google store the same data? and if so, when did they start?
