As Callum Haywood explains on the About page of his site, his tool “simply queries Facebook's Graph API and outputs the results. There is nothing on this website that cannot be accessed by anyone else.”
Haywood told CNN that he decided to put up the site to raise awareness about posting embarrassing or even job-jeopardizing information on Facebook without enabling privacy settings.
“The people featured on the site are most likely not aware that what they post as 'public' can be seen by absolutely anybody, and that Facebook will happily give away this information to other websites via its Graph API", he explained.
Haywood has created four buckets of Facebook posts: Who wants to be fired?, Who’s hungover?, Who’s taking drugs?, and Who’s got a new phone number?
The most interesting from a career perspective is the Who wants to be fired bucket?, which contains rants from employees who “hate” their boss. In one post, Anastasia threatens to kill her boss: “Im getting so mad right now I hate my boss Jay I hope he dies better yet I feel like killin him if you in a bad mood don't take it out on everyone at the job like wtf its way to hot to take your sh**.”
Haywood stresses that he has made an effort to remove personal identifying data from the posts, such as last names, phone numbers, etc. He advises Facebook users to “make sure your Facebook privacy settings are sufficient, for example, don't publish status updates containing potentially risky material as 'Public' because then they have a good chance of showing up in the public Graph API.”
