A 15-year-old Florida girl's MySpace page has been hijacked and defaced with sexually explicit and hateful content, Tampa Bay affiliate FOX 13 reported, raising questions about security on Internet networking sites and what is being done to improve it.

The Oldsmar, Fla. teenager, who identified herself to FOX 13 only as "Becky," believes her page was taken over by a group of former friends. She says she can no longer access the page or take it down, even though it still bears her name.

Becky's mother says she has contacted MySpace, but has yet to hear from anyone or receive any help. She warned other teenagers to protect themselves from similar attacks by remaining vigilant and keeping their passwords to themselves.

In the meantime, Becky had a message for her tormentors and cyberbullies everywhere.

"I just want them to know that they need to think about other people's feelings," she said.
