ShoutBloger: Facebook tried to get its users to work together to improve Web site security system. Their latest offering reward of $500 for those who find bugs or loopholes in the Facebook site that are likely to divulge personal information to its users.
If you have found a problem on Facebook site, tell them. Facebook has made a portal called white hats, Researchers, and write down anyone who helped them in the portal.
However, bugs or problems you find are not derived from the Facebook site, or in other words from a third party, you will not get money in return. For example, if you encounter problems in the game's built-in Facebook, then Facebook will not give in return.
In addition, Facebook offers only one return for one bug. So who is faster to find a bug, then he is rewarded.
