Scrapers and duplicate content
 Trying AdSense links recently, 3 out of 4 links ended to scrapers or no-
content, empty sites, displaying only AdSense advertisement
 … putting us all on an equal playing field, at least where these links are
concerned
Google and other search engines are pretty good at determining where a
page originated
