A Web site founded by a Duke Univerity alumnus is stirring up controversy on several college campuses across the country.

The site, called Juicy Campus, features endless threads of anonymous innuendo. In some instances, the threads make references to students' sexual behavior. It's launched on seven college campuses, including Duke. It recently expanded to 50 more.

While some students have defended the site, there appears to be a growing backlash.

Student leaders, newspaper editorials and posters on the site are fighting back, with some even asking administrators to ban Juicy Campus.

The founder, Matt Ivester, said he has rejected calls from schools, including Duke, to shut down the site. He said he thinks the site can have a positive impact on college campuses, as a place for both entertainment and free expression.
