My pleasure. Yes its an offence here, although they exist, people go out of their way, break the law so that they can send their message.
I had a friend way back around Five year ago, He love to do graffiti, he buys spray paints and keep them till its late at night, and we would all go out and look out for him while he does his work. the experience was fun tho,and seeing those art everyday and remembering how it got there really makes me smile.
