I have been asked by several people why I don't show my face in my pictures.
The simple reason is that my previous account attracted a couple of weirdos, one of whom employed his considerable detective skills to pursue me across the internet.
So I deleted my account, started again, and left all of my old pictures off DA. It seems to have worked - no idiots in a couple of years now.
So that's why - I'm not ugly or anything. Honest.
