MyYearbook.com Invasion of privacy, what amounts to stalking, uninvited advances, offensive comments, data theft, character asassination Internet

Without any involvement from me, I was "attacked" on a "friend's " facebook page with an offensive question through MyYearbook. As a result I deactivated my face book account immediately. However I was subsequently inundated with a barrage of friend requests, marriage proposals, invasive and inappropriate questions via MyYearbook. In addition it would seem that they managed to access data about me that I have endeavoured to keep private, and I am also suspicious that they have somehow managed to retrieve images that were not in the public domain.
