Another day, another Facebook privacy story in the headlines. It seems that the problem with Facebook privacy is not so much the facilities that Facebook offers, but more the understanding of these facilities by the people that use it. 

You would think common sense would prevail in most cases, and that people wouldn't publish their full address details online and invite people to a party... but they have done, and still continue to do so. The latest case involves a 15 year old girl in Hertfordshire who wanted to invite 15 friends to party, only to receive 21,000 responses. 

Despite the original invite being taken down, re-posted versions of the invitation continue to resurface. Police will now be patrolling the area on the night of the party to ensure legions of gatecrashers don't disturb a dozen girls at a pyjama party. 

Facebook haters and privacy campaigners will no doubt use this as an opportunity to criticise what they perceive as over-complicated privacy settings that mean people share more than they intended. Although quite what is over complicated about a button that says: "anyone can view and RSVP (public event)" remains to be explained.
