Vandalism

[NoraB]

At least the older 'Z woz 'ere'-type tags, though still a nuisance, were more easily understood, more relatable,

I had a job as a cleaner once. It involved tackling the men's loos (always a pleasure, not) and one day somebody scrawled, 'I'd shag the cleaner' on the cubicle door. I think they meant me, though they could also have been referring to the previous cleaner who was 65, and a bloke.
