"In a nice example of how Facebook's bounty program should work (in contrast with that mess a few weeks ago), a security researcher has unearthed a bug that would let anyone delete just about any photo from Facebook — whether the photo was yours, mine, or Zuckerberg’s — and was paid a solid chunk of cash for the discovery.
According to the terms of Facebook’s white hat program, those who find bugs and follow Facebook’s rules in reporting them are paid a bounty. The minimum bounty for any bug is set at $500, with Facebook paying more based on the bug’s severity. Most payouts I’ve heard of tend to be around $1,500. In his write up of this bug, security researcher Arul Kumar says he was paid $12,500 — roughly 25x the base bounty."
Since basically everyone has a facebook and this happens to involve the photos you post under your name. Reading about this, will help you to be aware and also to protect your own photos.
