While I generally agree with the sentiment that facebook and job sites are like oil and water, how would discrimination with this tool work differently than just searching for an applicant on facebook today? I wouldn't imagine this information would be surfaced alongside the resume, so it would still require an employer to actively take steps to discriminate.
It's different because you can set your profile privacy to "Friends Only" so prospective employers can't look at your info. Facebook, however, has access to all that data and who knows if/how they might discriminate (doubtful it would be explicit/intentional, but it's easy to accidentally let bias creep into machine learning algorithms).
Wouldn't Facebook be the single best equipped company to stop potential discrimination?
E.g. You submit an application for a job posting - once that application is opened, Facebook could block anyone who has used that IP in the past 30 days from accessing your profile.
I imagine Facebook is where most publicly accessible personal data is, if they could be compelled to, by PR or law, they could dramatically curb discrimination.
That would be trivial to circumvent (pick up your phone and browse their profile from that) and would have false negatives (large company with many users behind NAT).
It's different because there weren't hundreds of people working on and marketing a tool that actively couples this behavior with actual hirings. Now, there are.
