New Filter Puts Adult Sites at 250,000

An Orange, Calif. software manufacturer claimed its new filter will keep Internet surfers from landing on more than 250,000 pornographic and sexually explicit server addresses stored in its ever-expanding database.\n Log-On Data Corp. (www.xstop.com), which makes X-Stop, said its filter is the only way a parent, teacher, librarian or business owner can keep up with the growing number of adult entertainment sites on the Internet. George Shih, company president, said he is "saddened that pornographic content continues to be a serious problem, both in volume and ease of access."\n At the company's Web site, the software is offered for $39.95. The company said it has taken two years using a custom search array to track down all the Web and Internet provider addresses on which porn lurks. After the custom search, called MudCrawler, identifies a site based on several criteria, an employee of the company verifies it to be sure it should be blocked. There is a patent pending on the search array technology.\n "We have to manually check the MudCrawler matches," Shih said. "But checking 2,000 to 5,000 new sites a day that have a pretty good chance of being sexually explicit is much more effective than slowly plowing through Web directories." From those checked, the company typically adds 300 to 500 sites a day to the list it will filter. In many cases, the content of more than one site may be identical with the content of another but the address is different.\n The best proof of MudCrawler's effectiveness is the number of addresses it finds that leads to a single site, Shih said.\n "We've found 14 percent more sexually explicit content online from January to June of this year, as opposed to last," the Log-On Data executive said. "Imagine anyone trying to catch all the new sites without a MudCrawler. You just can't do it."
