Confession time: it took a long time for me to realize that the ubiquitous Kotsy tags in Kotsy's photos were Kotsy's watermark.
I just thought there was some prolific tagger called Kotsy running rampant in the city whose tags kept showing up in... Kotsy's posts. Oh....
For a time I even wondered if Kotsy was still actually a real graffiti artist who also liked buildings and deliberately tagged where it would be visible from their drone.
It's a good thing travelling carnivals aren't really a thing anymore, because I would absolutely have fallen for all sorts of carny flimflammery before belatedly realizing I was a mark.
