Oh, I know it happens. I'm surprised that people post anything online under their real names (my real name isn't War Hamster). The only thing I ever posted on FB before I deleted my account was diving videos, and I don't even have an HR department to worry about.

HR people are the Uber-Karens. It's one thing to go through public posts, but when they start digging into your private communications.....that's where this is going.
