NEW YORK (CNNMoney.com) - States seeking payments of delinquent taxes are trying to use a combination of Internet technology and shame to get scofflaws to pay.

At least 19 states and the District of Columbia are listing or plan to list people and businesses who owe taxes on their Web sites. Many have names to try to capture attention and bring more pressure on delinquent taxpayers.

Maryland has a "Caught in the Web" site to list those who owe state taxes, while Louisiana has "CyberShame." South Carolina's site is called "Debtor's Corner."

USA Today reported Friday that the sites are helping states to collect money owed to them. Georgia's online delinquent tax list has collected at least $19.6 million since it went up in February 2004, and Colorado's Web site has raked in $11 million, according to the newspaper.

The newspaper reports that the states send notices to the delinquent taxpayers that they are due to go up on the Web site, and that can help bring the payment.

Wisconsin Department of Revenue recently sent to more than 7,000 people and businesses who owe the state at least $25,000 each in sales, income, corporate or other taxes, according to the report. The threat of online exposure led to least 88 Wisconsin residents and 21 businesses agreeing to settle debts totaling $7.9 million, according to the report, even though the state's delinquent taxpayer site won't go live on the Web until Jan. 3.

"The real success of the program is before the postings are made," Geraldine Conrad, spokeswoman for the Illinois Department of Revenue, told the newspaper. "People are motivated to pay."

All the sites have information for taxpayers listed about how to get off the site. The Minnesota site, DelinqNet, has temporarily pulled its complete list as it completes an evaluation of compliance activities, according to the site.

It's not clear how visible these sites really are. While Louisiana's and South Carolina's sites can be found easily with a Google search of their name, Maryland's site is tough to find even with the search engine.

And using terms such as "South Carolina delinquent taxes" in the search engine doesn't easily turn up Debtor's Corner.

Connecticut, which is credited with being first with an online delinquent taxpayer list, changed the location of its Internet listing without a forwarding link, even though the old address is still on the "Spies Online" Web site that includes links to various state's scofflaw listings.

The Internet address the Connecticut listing formerly had now has only the notice: "The requested article is no longer published." The listing is at a different location on the state's Web site.
