Jacqui Cheng for Ars Technica:
Facebook is still working on deleting photos from its servers in a timely manner nearly three years after Ars first brought attention to the topic. The company admitted on Friday that its older systems for storing uploaded content "did not always delete images from content delivery networks in a reasonable period of time even though they were immediately removed from the site," but said it's currently finishing up a newer system that makes the process much quicker. In the meantime, photos that users thought they "deleted" from the social network months or even years ago remain accessible via direct link.
Amidst all the discussions of Internet privacy lately, it's disconcerting to hear that such a gaping flaw still persists today. Given the amount of money Facebook is vacuuming into its accounts, you would think they could afford to correct such a high profile issue.
