Developers from 16 different countries has contributed their work to the social media and has paid a single hacker $7000 for a total of 6 contributions.
Facebook pays out rewards ranging from $500 to $5000, estimated by the severity of the bug, and up until now there has been some confusion where rumors had said that the maximum payout was $500. There has only been paid a single reward of $5000 but a lot of the $500 payouts, Facebook has announced that even though they are very satisfied with the program there still are many people who contribute useless reports just to get publicity.
This type of initiative is not uncommon for big IT corporations, companies like Microsoft, Mozilla and Google each has their similar program, where Google has paid out more than $300,000 during the lifespan of their program and Microsoft who has promised $250,000 for those who can develop security tools that will protect Windows users against attacks that exploit software.
