Have you ever posted some photos on the Facebook, but later you may have regretted doing so and may have deleted them? But hold your breath - some deleted Facebook photos can still be accessible via a direct link.

Ars Technica had found the terrible fact more than three years ago but the problem still persists. Facebook is aware of the problem and said the company has made efforts to resolve it.

When Ars Technica's Jacqui Cheng found out the problem in 2009, she had asked the social network about it. At that time, the company said it was working with our content delivery network (CDN) partner to significantly reduce the amount of time that backup copies persist.

However, in 2010 the problem wasn't resolved, and the readers of the site recounted many terrible stories relating to the deleted photos that never actually disappeared from the Facebook.

When Cheng contacted the social network and asked why the problem has remained for so long, Facebook spokesperson Frederic Wolens replied via email, The systems we used for photo storage a few years ago did not always delete images from content delivery networks in a reasonable period of time even though they were immediately removed from the site.

Wolens also assured the company will resolve the issue within a month and a half. He said they are working on the new system, which will finish soon and run within the next month or two.

We have been working hard to move our photo storage to newer systems which do ensure photos are fully deleted within 45 days of the removal request being received, Wolens said. Do you think the embarrassing old photos will be deleted permanently this time? Leave your comments below.
