Placing ads on pages with only several sentences of content(huge websites maybe exception to this because of the uncontrollable number of pages. The percent of good pages to bads is the key)

This could be a dangerous assumption.

If a website has an uncontrollable number of pages then that is their problem, not Google's. Web pages that have no content and that carry Adsense are no use to anyone apart from their owners and they are operating in contravention of Adsense policy. Surely the size of the site is of no consequence?
