Rant - Sad Nicknames

Someone with the nickname of "cockjerk" just sent me a friend request. This individual was obviously thinking with the wrong head or wasn't thinking at all when he chose that nickname. Why would anyone pick a nickname like that for your profile at a site for nudism? I am sure there are many others out there with similar nicknames. Keep them to yourselves, I don't care to know of them. Thanks for allowing me to rant.
