The most innocuous of social media interactions can have negative consequences. A case in point: Rory Cullinan, the outgoing chairman of the Royal Bank of Scotland. According to Time, Cullinan was mocked roundly in British tabloids when it was discovered that he had sent several Snapchat selfies to his 18-year-old daughter with captions that expressed considerable distaste about the board meetings he was attending at the time. (Some examples: “Boring meeting xx” and “Another friggin meeting.”) Though Snapchat messages disappear after a short while, Cullinan’s daughter posted them to her Instagram account, giving them a second life. Soon after the messages went viral, RBS announced that Cullinan would be stepping down at the end of the month, though it did not give a reason for his departure.
