You dont use braided lines for anchor ropes. No stretch, so they snatch at the boat. And generally they are sinking lines, which lay on the bottom and catch under every bommie in the area.
Yachties like bright work on their boats so fender ropes and mooring lines might get the brush treatment.
Or otherwise you could be constantly on the move cleaning haliyards and reefings
