Answer 1

It is most likely vandalism

Answer 2

y'know, i've been an artist all my life, i don't do graf, but i do collect it and i have nothing but respect for graf writers.

it is art, it is wonderful marvelous colorful art.

it beats the dickens outta drab grey concrete walls.

Answer 3

if the building is abandoned or if he has permission, then I'd call him an artist.  If the building is being used the artist doesnt have permission, then hes a criminal.
