"hasn't tagged in a while", ...sorry to say but it's likely he will again. Why? Because he either doesn't understand boundaries or disrespects them. How do make it ok to vandalize property that is not your own? What would be interesting...is to locate something that has significant meaning and importance to Mr. Bansky and vandalize the heck out of it. Would he have a "painful" reaction to this assault? I for one would hope so.
