Not in the form of exposing someone. If I'm in a group chat and someone says something stupid, I screenshoot it and send it to my friend and we cackle at the stupidity.
Once I actually took a screenshot of a chat with person X to send it to a mutual friend Y (my friend Y and I both disliked that person X but he kept talking to us) Anyway, I messed up and instead of sending the pics to Y I sent it to X.

my heart skipped several beats.
