Inverse graffiti: use cleaning solvent, not paint

A Yorkshire graffiti writer has come up with a really clever writing technique: he lays a template with his tag over a dirty wall, then sprays the template with solvent, leaving behind a clean patch bearing his message. It's inverse graffiti -- he's selectively cleaning up dirty walls.

He decided to commercialize the process and tagged Smirnoff ads in Leeds, and that's where he got into trouble: he's been ordered to "remove" the clean patch of wall and get rid of the ad.
