Or if they do exist - everyone who has a copy is being smart and not sharing due to legal reasons e.g. Noone wants to be met with legal docs for something they posted on LPSG?

As much as I hate to say it. We gotta respect it if someone can't share their saved pics.

Feel free to message them privately. But probs shouldn't hold your breath around the idea of people sharing via public posts cause Australian laws are starting to crack down on that stuff (correctly - revenge porn is a thing and should be punished imo)
