The Data Protection Commissioner Billy Hawkes is calling for better awareness of privacy settings on Facebook and other Social Media sites.
Mr Hawkes was commenting after a High Court Judge refused to grant an order stopping newspapers from identifying a DCU student, after he claimed an online video defamed him.
The student sought the injunction after he was wrongly identified as the man in an online video showing taxi fare evasion.
Commissioner Billy Hawkes has said there should be better information for Facebook users about protecting themselves online.
Mr Hawkes said: "We recently carried out an audit of Facebook, which comes under our jursidiction, and one of our recommendations is that there should be greater information for people when they use Facebook (and) the risks they run in doing so.
"They should get better information on how you can in fact protect yourself on Facebook in terms of the privacy settings, they are there to be used."
