A 17-year-old boy allegedly hijacked a facebook birthday party invitation originally posted by an Australian teen named Jess, which resulted in 214,000 people accepting the invitation to the party at her house on March 26.

Jess who’s celebrating her 16th birthday intended to invite only the students in her grade, but told her guests that they could bring friends since she didn’t have time to invite everyone. She even encouraged others to invite friends on her behalf saying that it was an “open house party as long as it doesn’t get out of hand.” The invitation, which went viral, had her address on it.

A number of the postings on the invitation’s wall used the Anonymous symbol in them, which appeared to have been hijacked by members of the notorious chat group Anonymous, resulting in it going viral worldwide.

The schoolgirl immediately reported that the site had been hijacked to the police. According to Jess’ father, she had invited a few friends, but didn’t know how to use the privacy settings on Facebook to stop strangers from seeing her party invite. “She was just anxious about whether anyone would show up to her birthday,” he said.

Moral Lesson of the story, learn how to use Facebook invites to keep the privacy settings ‘PRIVATE.’
