Posts about hot resident assistants and unsubstantiated rape allegations float around JuicyCampus.com — a website advertising its student-posted content as “always anonymous and always juicy” — irking and embarrassing administrators and students at some schools, including Boston University.

The website, launched last August by Duke University 2005 graduate Matt Ivester, has sullied enough reputations that students at some colleges have petitioned administrators to block access to the site through on-campus Internet networks. The student government at Pepperdine University passed a resolution last month encouraging the school to ban the site from on-campus severs, though it has not yet done so.

According to Pepperdine’s student newspaper The Graphic, Internet privacy lawyer Parry Aftab said the website could be violating laws if it does not provide the anonymity that it advertises.

BU spokesman Colin Riley said the administration may not be able to ban the website because of the school’s stance on academic and expressive freedoms, but students should avoid the site anyway.

“The type of character who would write on that site is not the intelligent, mature Boston University student I imagine,” he said. “It is the Internet equivalent to writing on a bathroom wall. But at least in a bathroom the writing can be painted over.”

The Student Union is aware of JuicyCampus.com but has not discussed banning the website from the university network, said Union Vice President John Dallas Grant.

“I personally believe that banning the website from the network would be a violation of our freedom of speech,” he said in an email. “Our students should always have the right to share their thoughts, not only with the BU community, but with anyone they choose.”

Grant said it is up to students to change the website’s atmosphere by not posting destructive gossip but instead using it in a positive way to “bring BU together, rather than tear it apart.”

“I hope that BU students remember that when they post on a website like JuicyCampus.com, that they represent not only themselves, but also our BU community as a whole,” he said.

College of General Studies sophomore Brooke Raskin said she has been personally targeted on the website’s BU forum. Raskin said the information about her on the site is false, and, as well, would not be of a public nature.

“The website isn’t about free speech. It’s about negative and hateful speech,” she said. “Unless there is a way to make the site positive, I definitely think it should be taken off of the Internet.”

Raskin said she did not find the rumors about her on the site, but was told about them by a friend. There is no way to delete it from the site, Raskin said.

“Before I even knew about it, other people knew,” she said. “And there’s no way to fix it.”

Loyola Marymount University-California sophomore Bryce Falcon created the Facebook group “JuicyCampus Rocks!” in response to the website’s opponents. He said officials locked down the school after an anonymous poster threatened to “shoot people on campus” last fall.

He said despite the offensive comments on the website, removing JuicyCampus from the Internet would not teach people to respect one another.

“I think this problem lies deeper than the site,” Falcon said “To solve it, we need to address the students themselves, not deny them this one medium for hateful expression.”

JuicyCampus creator Ivestor could not be reached for comment.
