Seems to me that this is a common problem after every big weekend. Very easy fix, move the camp away from the fingers and don't use them to access the dunes. I never have an issue with this because I don't camp near the fingers. I am not saying that what happens is right but the truth of the matter is that you cannot change azzhole's behavior. I go to the dunes to relax and have fun, if your not doing this either move your camp or get over it.
Just don't move your camp near mine cause I like peace and quiet!
