Emily, I can see that if this man is making a constant nuisance of himself then it must be incredibly annoying, but the ones that ring/email and talk about how huge their cock is are about the most common timewasting callers we get (after the 'my mate gave me your number' ones, anyway). I suspect that everyone who works within 100 miles will have heard from him at one time or another, and if you block his numbers/email address and ignore him completely he'll move on quickly enough.
