You should do the best you can. How would you like to be treated if the shoe was on the other foot? IfI knew a guy's blind was there I would give him some space just incase he showed up. Many years ago, I was up in a treestand in the dark when a guy comes in with a flash light and sets up on the ground against a tree 40 yards from me. He knows I'm there and stays the morning. I'm 20 feet up, I can see where he can't. I shoot, he never even sees what I am shooting at. Eventually he left after a few hours. Not a very fun way to hunt.
