then don't send them, but don't complain about facebook allowing your nudes to be posted. I don't think Facebook is going to open source their image recognition algorithm just because you want it to. You do have a choice, use the service or not. If I ever found out a nude picture of me was leaked, I'd definitely trust FB more than whoever took it and leaked it in the first place. The whole point of the service is pretty much: your picture is already or about to be out there.
