What concern's me is that this seems to have become accepted. Look at all the scraper sites. They put in a link to me when they copy and publish a snippet from my site. Google links to me when they publish the cached version of my page. Neither one resembles what I thought 'fair use' meant.
I don't have a problem with my site being cached but publishing it must be a copyright violation. I could live with search engines doing it but it seems to be opening it up to everyone else.
First search engines used a snippet to describe my site. Now thousands of scrapers do as well. They will just claim they are providing search information. So now hundreds if not thousands of pages on the internet are using info from my sites.
So maybe the whole thing needs to be revisited. I don't have any answers but I'd sure like to see a solution.
