Would you share pictures of your ex online?

Um, what the hell? No, that's messed up man. Revenge porn is being pushed to be a federal offense for a damn reason, and ist least a misdemeanor in many states, and sfw pictures are still just a massive dick move. Check yourself, maybe go deek therapy, because it's not normal nor remotely OK to want to do that enough to actually consider doing it.

If this is how you respond to a breakup, you're their ex for good reason.
