I'm not worried about our new friend. At least he is entertaining. If he is a troll he will eventually go away when he realizes he is preying on the wrong group of people, but if he is seriously legit then he can always learn from this group as well. Any sane person knows hanging a scarf on a tree isn't going to tighten up your bass (or some other far fetched idea) so I really don't see the harm he is causing except for maybe making us read a few ridiculous posts here and there.
