"Their work is, by nature, uncredited." Uhm... Most graffiti is actually just a tag, the artist's tag. So, most graffiti is literally just the artists credit. And, by definition, they are vandals, not heroes.

How is that the definition of vandalism? I think that depends on intent and on the result, which is subjective.
