Each alum agrees to how much information can be released to other alums and to the general public.  Whether you think it is stalking is irrelevant.  I believe you are throwing allegations of stalking because you are a petulant little boy who is stamping his feet because he didn't get his way.  You need metaphorically pantsed, your glasses thumbed, and your milk spilled.  Now go pull some wings off of flies, you weirdo.
