How to fix URL typo scams

At Slate, Paul Boutin offers an interesting set of suggestions on how to fix URL typo scams.

Various studies have estimated that 10 percent to 20 percent of all hand-entered URLs are mistyped, adding up to at least 20 million wrong numbers per day. From my own experience that sounds about right—I can spell just fine but I leave out characters, transpose them, or hit the wrong key at least 10 times a day. No wonder wave after wave of entrepreneurs have fought to tap that flow and turn it into cash.

So, are we just doomed to suffer one typo traffic scam after another? Only until someone makes a software program that lets me control what to do with my typos. Here’s a simple design spec. First, intercept obvious, punctuation-challenged goofs like wwwslate.com. Second, recognize when a URL isn’t resolved by domain-name servers by detecting when Internet Explorer, Paxfire, or any other known culprit tries to serve a landing page. Third, keep a database of typo-trap URLs like htobot.com. And lastly, I should be able to manually configure the software to handle my habitual mistakes—whenever I type markrobinson.com, give me markrobinson.org instead.

Interesting idea. Actually, I’m surprised there isn’t a Firefox extension for this already!
