I believe the Question Marks are leading us down the wrong path

As the title suggests, I think the question marks are leading us down the wrong path.

The reason why I think that is because so far every clue has pointed us into a certain direction. Of course the clues like ''N (Telephone pole)'' in the middle of the spider. The ''W +++++'' clue. The ''NW (Guitar)'' clue. I am a bit skeptic about the birds but they still lead us in some form of direction. But as far as I know the Question Marks do not in any form.

I have seen players report question marks on completely different parts of the map. And while it definitely looks like a clear question mark, I think it is more of a coincidence than an actual clue.

I'll be trying to figure out if the ''Guitar'' may perhaps lead to something else, but I wanted to hear some second opinions. What do you think?
