CBS/AP) Federal agents swooping down on a motel room in Hollywood, Florida, have made legal history with the arrest of John Zuccarini, 53, who is accused of using thousands of deliberately misspelled Web sites to lure children to porn sites.

Authorities say Zuccarini, who is being held without bail, made as much as a million dollars a year from the ad revenue he got from porn sites when he successfully tricked Web surfers into visiting sites with misspelled names of people and things popular with kids, including Teletubbies, Bob The Builder, Disney and Britney Spears.

Zuccarini is not a new face in alleged misuse of domain names. The feds have been on his trail for four years and say he's lost 53 state and federal lawsuits and has had about 200 Web addresses taken from him.

What is new is the strategy being used by prosecutors, who are making him the first person ever to be charged under the Truth in Domain Names Act, which is part of the new Amber Alert law for finding missing children.

Zuccarini "is accused of taking advantage of children's common mistakes, and using that to profit by leading them by the hand into the seediest and most repugnant corners of cyberspace," says James Comey, the U.S. Attorney for the Southern District of New York. "His alleged actions are not clever but criminal."

Using a misleading Web address to draw children to pornography is a crime punishable by up to four years in prison and a fine of $250,000.

Prosecutors charge that attracting kids was no accident in this case and note that "Teletubbies" and "Bob The Builder" are both popular with children under ten years old.

In court papers, prosecutors furthermore say that in connection with civil lawsuits filed by individuals whose domain names were exploited, Zuccarini "admitted that one reason why he registered domain names of Web sites popular with children is because children are more likely than adults to make spelling errors and to mistype Web site addresses."

Winding up at the porn site was only the beginning for kids who took the bait, according to prosecutors who say efforts to close the browser window or use the back button instead triggered pop-up ads for more porn.

The often-used technique for trapping Web surfers - known as "mousetrapping" - makes it nearly impossible to close the window of the site the user is trying to leave.

Zuccarini is due back in court in Fort Lauderdale on Friday, at which time an attorney is expected to be appointed for him.

A host of federal agencies and agents cooperated in the investigation of Zuccarini, including the U.S. Postal Inspection Service, the Federal Trade Commission's Bureau of Consumer Protection, and the Department of Justice's unit on Child Exploitation and Obscenity.

Authorities in New York say they may ask for his return to face prosecution there.

The FTC has done battle with Zuccarini before.

Companies who claim that their names were exploited by the alleged misspelling scheme have filed dozens of complaints with regulators and the oversight body that doles out Internet addresses.

The sheer volume of complaints involving Zuccarini sets him in a class by himself, according to Marc Groman, an attorney in the FTC's Bureau of Consumer Protection.

"I am not aware of others who have done it on the scale of Zuccarini," says Groman.

Last year, after being sued by the FTC, Zuccarini was ordered to stop operating Web sites using misspellings of the bubblegum pop group Backstreet Boys, the Victoria's Secret women's clothing catalogue, and The Wall Street Journal.
