Sure but that rules out most kinds of ads. Even contracting directly with clients to show their ads, the client is often going to want to run the ads through a third party server so they can easily track all the different campaign they&#x27;re running and check that the publisher is providing as many impressions as promised.<p>I think basically you&#x27;d end up with a lot of sponsored content and &quot;Brought to you by...&quot; type sponsorships interwoven in the site so they cannot easily be blocked.
