Why do they have to spend money clearing up after them? Does 'well

How much is well done? Mostly it's a simple tag, which requires no
skill (take a pen and paper, now scribble some initials or a name; hey
presto.. your very own tag).

I'd agree that some stuff you see doesn't look too bad, but it's not up
to you or I to decide whether we should be 'adding to the character of
an area'. Covering the cab window of a train probably isn't
particularly safe either.

More important though is the fact that people don't feel safe around
graffitti, even if a lot of it is done when they're not there (rather
than the image of a train being attacked with helpless passengers
looking on).
