Typosquatting: This happens when an Internet user looking for, say, e-bookseller Amazon.com may type in "Amazom" by mistake and ends up at a bookshop run by a rival company. Typosquatters draw away valuable business from the original domain name owner.

However, little has been discussed about a growing species of cybersquatter, called the "typosquatter." Instead of registering domain names containing the trademarks of others, typosquatters first determine what Web sites are attracting the most traffic and then register for themselves domain names that consist of the likeliest typographical errors that users may make when seeking access to the high-profile sites.

However, little has been said about an interesting and growing subspecies of cybersquatter: the 'typosquatter.'…Typosquatters look around and see which Web sites get the heaviest traffic. They then register, for themselves, domain names that consist of the likeliest typographical errors that users make when seeking to access these sites. In other words, someone looking to call up Microsoft's site may type Mocrosoft.com by mistake. So the typosquatter registers the domain name mocrosoft.com.
Subscriber Neil Ferguson told me about this word.
