Facebook launched Hacker Plus, the first-ever loyalty program for a tech company's bug bounty platform.

Any researcher who submitted or submits bug reports to Facebook will be included.
Based quantity, score, and signal-to-noise ratio of their bug submissions over the last year, bug hunters will be placed inside one of five tiers (leagues): Bronze, Silver, Gold, Platinum, and Diamond.
On top of the regular bug bounty reward, hunters in Bronze League will get 5% bonus while hunters in Diamond league will get 20% bonus.
Hunters above Silver league will also get invites to stress-test new features before launch.
Facebook also released a new tool called Facebook Bug Description Language (FBDL) for hunters to use to resolve bugs faster and maybe get another monetary benefit.
