Ok I have this very elaborate plan for stalker removal. You will have 2 choices, please know these methods are guaranteed to work but are not recommended by me:
Option 1: You use an IP identifying program to locate this stalker and once found you go to his house, hide somewhere near, wait for him to come out, take a picture of him, photoshop him (remove his clothes with some editing), if he is a guy, remove penis on picture if he is a girl remove boobs, then patiently wait until he goes to school or work. Once you know what school or work he goes to post a myTake here stating that you furrently have a picture of him naked with no privates, post the pic on here, threaten him saying that you will post this picture on his school Facebook wall or at his works page or to his colleagues pages (which you will have to find out who they are) if he doesn't leave you alone. Also state that if he does, you will remove the pic from online and delete the picture (but dont actually do it in case he lies keep a copy). If he fails to comply or lied proceed to post images on Facebook.
Option 2: Ignore him. Block him once you know who he is.
