The case below highlights the danger of posting any potentially sensitive information online. In a nutshell an angry bank customer posted info via Twitter which was used to pose as the bank trying to sort out his issue. He nearly lost £8,000 but fortunately the transfer was stopped.
The lesson here is be careful what you post as even a small detail like your name and nature of the complaint can be enough to leave you exposed. Hopefully the bank concerned will also learn from this.
