But it's not enabled on all pages in Chrome unless you install an extension. By default, Chrome enables built-in ad blocking on specific set of sites that they consider intrusive.

> The only reason to ever discriminate between pages is when one has actually committed a crime (e.g. the safe browsing lists)

Careful, I don't think you're gonna get to see the criminal complaint for all on the safe browsing list. Or you you mean committed a crime in Google's eyes?
