we have someone who took a screenshot of a customer account, grayed out the persons name and account number, but left the city and account balance and posted a copy with "anyone in this city needing a sugar mama should look her up"

no doubt, and easily defensible. many companies have also developed social media guidelines for employees because anyone saying the wrong thing to the wrong person could start a firestorm of backlash.
