Exactly. The message here is more along the lines of “pity this was painted over so boringly, this is what you get”. It is not just a wall, it is the wall with the original artwork still underneath a thin layer of paint. I call art. Even with just the “hehe”, I’d say it still has the old meaning of any mark made on purpose anywhere: “I was here.” (That seems to be the main point of tagging.)
