"Dirty Saint" did write 7 messages saying "I'm outside your window."
"Dirty Saint" and "xXYoutubeXx" aren't the first people to try to trigger my "paranoia." People do that all the time; they think it's funny.
More people than tend to be acknowledged like to try to upset "crazy" people. If they know that someone has called you crazy, they will try to figure out what will trigger you, and they will harass you. Ignoring them doesn't help; if you ignore them, they take that to mean that they can continue to harass you. If you ask an authority to tell them to stop, you need other people to verify to the authority that you're telling the truth; your word against the bullies is never enough. It's not as if people who enjoy bullying are hesitant to lie about it.
