Victory! Facebook has pledged to address photo privacy concerns. "We're currently working with the CDN [content delivery network] on a fix that will delete photo and video content from the CDN's cache shortly after it's removed on Facebook," a Facebook spokesman wrote Change.org on October 20. "The fix is already in place for videos, and we hope to implement it for profile pictures and photos in the coming weeks."

You may think deleting a photo from Facebook wipes it out of existence, but it doesn't. In October 2010, Ars Technica blogger Jacqui Cheng found that a photo she had deleted from Facebook 16 months ago was still on Facebook's servers. 

The first step to keeping incriminating information off the Internet is to not put it there in the first place. But what about those who delete inappropriate photos, only to find out that the photos are still being held indefinitely on Facebook's servers? Teachers, students, job applicants and workers of all trades risk being fired or suspended if information about them surfaces on Facebook.

Tell Facebook to clarify its photo deletion policy, and to truly delete photos that users have deleted.
