Nono, it was there when I came to the site. They had left some lines hanging from the nail as well, could have been used for a tarp. Most likely not hammockers though. I just don't see a reason for anyone to do that whichever way you camp - you have to tie a knot whichever way you do it, and it seems more work to hammer a nail into a tree than wrap a line around it..
