The next time you try to upload a photo to Facebook, you should probably think about it… The reason? Because even if you delete it from your account, it will remain on Facebook servers, still accessible to third parties…
As the ArsTechnica website reveals, in case someone keeps the link of your photo, they will continue to access it even three years after you have deleted it.
This revelation comes a few months after Facebook's official commitment to correct its security policy. According to a company spokesperson, the new photo system is close to completion and only a small number of photos are available after deletion.
Few or many, the issue should be resolved as soon as possible, because when someone chooses "Delete This Photo", he wants to delete his photos immediately and completely.
