No mystery - it happens if you create a new account and stop using the old one. Actually I spend a lot of time debating with myself and criticising my work so it could have been handy.
I'm mellowing a bit in my old age and allowing people to do fairly silly things which I would have been abrasive about in my youth. Funny that it makes the systems more difficult to maintain and inefficient but the clients seem happier - which unfortunately makes it more difficult to end contracts. Being right too quickly often isn't appreciated.
