Obvious facebook downloads question

Just wanted to gauge how the forum feels about these.

You can tell they are face book downloads from the huge scrambled file names.

For example 5920_718651115408_16712871_41664370_4145462_n

Usually pics you took yourself will have DSC or IMG depending on the camera.

I won't shop pictures that don't appear original based on file name. I feel that it is not consensual with subject being blacked so to speak.

What do ya'll think?
