@Marco_Piani @zorinaq @GidMK @elonmusk Setting aside illegality fo graffiti aspect, I don't think you have standing to complain. Someone could stand behind you or next to you with insulting signs for example. That's the nature of a pubic square.
@Marco_Piani@zorinaq@GidMK@elonmusk抛开涂鸦方面的违法性不谈，我认为你没有资格抱怨。例如，有人可能站在你身后或你旁边，用侮辱性的手势。这就是公共广场的本质。
