Asbury Park- When students post their faces, personal diaries and gossip on Web sites like Myspace.com and Xanga.com, it is not simply harmless teen fun, according to one Sussex County Catholic school principal.

It’s an open invitation to predators and an activity that Pope John XIII Regional High School in Sparta will no longer tolerate, the Rev. Kieran McHugh told a packed assembly of 900 high school students two weeks ago.

Effective immediately, and over student complaints, the teens were told to dismantle their Myspace.com accounts or similar sites with personal profiles and blogs. Defy the order and face suspension, students were told.

While public and private schools routinely block access to noneducational Web sites on school computers, Pope John’s order reaches into students’ homes.

The primary impetus behind the ban is to protect students, McHugh said. The Web sites, popular forums for students to blog about their lives and feelings about their teachers and schools, are fertile ground for sexual predators to gather information about children, he said.

Students, who asked to remain anonymous out of concern for disciplinary action, said the majority of the student body protested the new rule. They tried to argue that they have freedom of speech and the school should not control what they do at home.

“The idea of a private school regulating student activity outside of school is not unheard of and there is a long tradition in it,” said Kevin Bankston, staff attorney for the Electronic Frontier Foundation, a San-Francisco-based defender of online civil liberties.

While Pope John’s school handbook does not specifically forbid students from creating personal profiles on Web sites, it does prohibit students from posting anything on the Internet pertaining to the school, without the school’s permission.

“It’s an incredible overreaction based on an unproven problem,” Bankston said. “If they’re concerned about safety, they could train students in what they should or shouldn’t put online. Kids shouldn’t be robbed of the primary communication tool of their generation.”

Bankston said he believes the real motivation for school officials was to suppress negative comments about the school posted by students.

One student, who identified himself as a senior who was expelled, wrote that “pope john kicks you out once you think freely.”
