Five people have filed a suit against Facebook in the US, charging the social-networking company with violating California privacy laws and false advertising.
Facebook users assume that personal information and photos that they post on the site are shared only with authorised friends, the suit, filed in the Superior Court for California in Orange County, says. "Users may be unaware that data they submit ... may be extracted and then shared, stored, licensed or downloaded by other persons or third parties they have not expressly authorised," the suit reads.
Writing and photos that people share on the internet are protected by law, so using that content without permission from the owner infringes on the creator's rights, the lawsuit alleges.
The suit describes at length a massive data mining operation at Facebook, which it says has transformed itself from a social-networking company to a data-mining company. It faults the company for collecting and analysing site content without user knowledge or consent.
The social-networking site said that it sees no merit to the suit and plans to fight it.
The Privacy Commission of Canada recently said that Facebook doesn't comply with Canada's privacy laws. That's after Facebook let users vote on one of two new terms of service options.
