Secret 'Facebook Stalker, Dark Profile and Judgebox' features revealed in new book

London, June 28 (ANI): Facebook had developed a feature, which would give secret accounts to people who did not even sign up to the social network, a new book has claims.

Katherine Losse, the author of The Boy Kings: A Journey into the Heart of the Social Network , claimed that engineers wanted to create shadow pages for those who were tagged in photos by their friends in the hope they would cave in and join the social networking website.

Losse, who worked for Facebook between 2005 and 2010, said that in the experimental feature named ' Dark Profile', people can be tagged in Facebook photos even if they do not have a profile.

The main purpose was to create a 'dark' version, which could apparently be activated if they finally signed up, The Daily Mail reports.

Losse also claimed that as recently as 2007 Facebook engineers were working on 'Judgebox' despite being obviously sexist.

The plan was to put two women's Facebook profile pictures side by side with space for a viewer to put a score for each.

The tagline was 'Judgebox.com: never judge a (face) book by her cover' and engineers registered the websites Judgebox.com and Prettyorwitty.com, though they never made it into the full version.

Zuckerberg had already developed such a programme at Harvard and called it Facemash.

According to the paper, the book also confirms for the first time that Facebook staff have a programme called ' Facebook Stalker' which lets them track who has been visiting their profiles. (ANI)
