When I post pictures here, I always make sure I mask the number plates as I believe I shouldn't post the identity of people's cars unless I have their express permission. I made one exception the other day when I posted a computer generated "drawing" of Joe's car, but I did so because his plate has been posted loads of times before and he has never complained. However, having said all this, I think masking does spoil the pictures. Furthermore, people photograph my car all the time when I'm out and about - usually with digital equipment - and I have no control over what they do with those images. So - what do people think - should plates be masked or not?
