The image is a riddle of some kind.
Question is by who, for whom and for which purpose.
Yellow banner on mini plastic flagpole depicting eight pieces of a snake similar to the 8kun symbol, with the words below it "join or 404".
What else is in eight pieces which can be joined?
What precice error does 404 point out.
Why is it used as filler for images recently not shown?
Not step on snek, only spitting my thoughts.
