No idea, I haven’t seen one (at least that I took notice of) BUT, does that man have a dog or a goat with him? I mean dog makes sense, but it really looks like a goat.
I don't really mind the ones that are painted on blank surfaces like on the backside of the freeway signs and near socro, but I do mind the ones painted directly on the trains. There's a few posts on his insta where he's tagged up an entire train with massive birds covering the windows, which forces trains to be pulled out of service and cleaned. He's even done a few directly onto the drivers cab windscreens, which forces the train to be taken out of service wherever it's noticed
