A civil suit filed in Florida by Dell and its Alienware subsidiary is giving insight into the enormous sums of money that can be made by creating Web pages full of advertising links.

In October, Dell sued a group of domain registrars, alleging the companies bought more than 1,100 domain names with trademark-infringing characteristics, such as "dellbatterrogram.com" in order to put advertising links on the pages.

The practice, known as typosquatting, is illegal. It's intended to draw unwitting Web surfers to pages with URLs that are similar to legitimate sites, and then redirect them to other sites. The owners of these Web sites get revenue from advertising referral programs every time a link is clicked.

The defendants -- Belgiumdomains, Capitoldomains, Domaindoorman, Netrian Ventures, iHoldings.com, Juan Pablo Vazquez and 10 unnamed defendants -- deny the claims. Dell contends the businesses, most of which are registered outside the U.S., are shell companies engaged in collusion.

Dell sought a court order in November to freeze their assets so the money from their operations wouldn't disappear. Last month, the court amended the freeze order, and contained in the details of the new order are clues to just how much money the defendants may be raking in.

Google, whose AdSense advertising-placement program was used to monetize the domains, was ordered to hold in a special account the first $1 million collected on behalf of the defendants each month. The second $1 million that accrues in the account every month will be given to the defendants. If more than $2 million accrues in one month, the money is split between the defendants and the Google account.

Google takes a cut of AdSense revenue, which shows that it in part benefits from this kind of abuse of the Internet. However, Google recently announced it will not allow AdSense campaigns on "kited" domains.

Kiting is a technique used by some rogue registrars to avoid having to pay the fee for using a domain. The domain is repeatedly registered and unregistered within a five-day Add-Grace Period. The grace period, which applies to a handful of TLDs (Top Level Domains) was intended to let people get a refund of their domain registration fee if they made a spelling mistake.
