Domain name front running
From Seo Wiki - Search Engine Optimization and Programming Languages
Domain name front running is the practice whereby a domain name registrar uses insider information to register domains for the purpose of re-selling them or earning revenue via ads placed on the domain's landing page. By registering the domains, the registrar locks out other potential registrars from selling the domain to a customer. The registrar typically takes advantage of the 5-day "domain tasting" trial period, where the domain can be locked without payment.
The term was created by domain investor and retired stockbroker Daniel Stager who likened the practice to front running, when a stockbroker illegally puts their own financial interests above that of their clients. ICANN has since picked up on the practice 
In January 2008 it was reported that Network Solutions uses data collected from their web-based WHOIS search to register every domain that users check for availability. Although the practice forces users to register the searched-for domains from Network Solutions, Network Solutions defends the practice, claiming that "This protection measure provides our customers the opportunity to register domains they have previously searched without the fear that the name will be already taken through Front Running." However, during the 4 day period the domain is still up for sale to the general public solely through Network Solutions and is not, in fact, reserved for a specific person at all.
