As part of its effort to prove that it's changed its ways following the Cambridge Analytica scandal, Facebook has announced a Data Abuse Bounty – a cash fee for anyone who can point the finger of blame at other apps developer misusing personal information.

The new reward is much like Facebook's existing Bug Bounty Program, which provides cash and kudos to experts who report potential security vulnerabilities and give the company time to fix them before telling anyone else.
