Best advice I've seen and one of the many virtues of this vice forum which I have taken to heart. I think anyone who leaves a trail either on a work phone, ISP or the like is taking serious and unnecessary risks. Personally I've written the name of an ex-co-worker on the box for my punting phone which I hide in plain sight in my desk drawer. If anyone was to see it my explanation is that he gave it to me before he left and I keep meaning to take it into work. Even so, I always delete everything off that phone. You cannot be too careful.
