I agree why get mad because sombody doesnt want to reveal there spot.
I have always found there are ways to take pics without photoshoping or revealing your spot. One of the best ways is to pull up next to some reeds and use them as a back ground. Knowbody will know where you were, just about all lakes have some reeds in them. Use those shots to post online and avoid people crying about it. Use the other shots for your own album.
