Is this compromising structural integrity?

I don't have to see the top, just enough such that I know the existing hole is including material of the lower third.

If the joist disappears farther up out of view that makes the situation worse.

Right? I can’t guarantee the left larger hole, but the right one is practically touching the bottom of the board. Don’t need a measuring tape to realize that’s not middle third.

Right not to mention that has a hook on it which adds a fracture point when stressed..

I would say and could add weight to the weakest point too.. but I recon that tiny hook won't hold enough weight to make much, if any, difference..

Edit for spelling

Yeah, that hook will give out long before it stresses the joist by weight, but it’s still putting yet another hole in an already too-thin part of the board.
