Are you sure there aren&#x27;t scams advertised in newspapers and on TV?  The main reason you see more scams online though isn&#x27;t (only) because of inferior vetting.  It&#x27;s mostly because online ads are much cheaper than TV, so the economics work out better for the scammers.  Same reason you get more spam in your inbox than your mailbox.  (And there are plenty of shady classified ads in newspapers.  You probably don&#x27;t see them because like most of us, you don&#x27;t read newspapers.)<p>Now, they do also do more manual vetting, but they can afford to, because again, the ads cost more.  Maybe online ads need to cost more too.  It just means that some fraction of the current legitimate advertisers will no longer have sustainable business models.
