Women 'deliberately post ugly photos of friends online'

Would you put unflattering photos of your friends on Facebook?The majority of women posting the photos said they did so after falling out with their friends, while nearly a third said they were taking revenge on people who had done the same to them.

Two fifths of women also admitted deliberately posting photographs of their friends without make-up. Even when asked to permanently delete the unflattering picture from Facebook, a fifth of women said they had refused to do so.

The survey of 1,500 women aged over 18 by Mymemory.com, a photo gift website, adds to growing evidence that people use Facebook to embarass or humiliate their friends.

While people can remove their names from pictures, they cannot delete the photograph.

Facebook has refused to get involved in the disputes, saying that unless photos have broken the site’s terms and conditions, individual users must find the solution to amongst themselves.
