One thing that might hook me is if you said which sites are scraped.
Best way I can describe it is "publicly allowable URLs on the web" which would include blogs, forums, social networks, websites, and more. If we can pick up the HTML/RSS/ATOM/Json/text.. then we try to get it.
We don't scrape any sites that disallow it in their robots txt and we don't scrape material only available behind logins and paywalls.
