Remember that embarrassing photo of you that you asked your friend to take down a couple years back? It may not be deleted. Arstechnica first reported and has been following up on a story of how Facebook's systems have not been deleting photos and are still accessible, even though Facebook has said they are gone.  Now 3 years later, it's the same story.

Frederic Wolens, a Facebook spokesman, said "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." The legacy system they are stored on right now didn't always delete the photos when they were supposed to, but this was just a small percentage.  He went on to say that the new system they are fine tuning will stop this issue once and for all.

The only problem I have with this is that they have said these kinds of things before and been caught in the lie. So are they really going to do it? Or is this just another line? After all, their business model is to sell info about us to advertisers to have targeted ads delivered. So I'm skeptical of this right now. But I still hope that at some point they will see the light and finally allow those photos to be removed. But as the saying goes, if it's on the internet, it's forever.
