Yes - by a student of mine. It started the summer before her 8th grade year. She would follow me around at my summer job (hey, I was making more money supervising lifeguards than I was teaching). It didn't matter what pool I was at or if I was at the waterpark for the day. She got my schedule from friends at the waterpark and would show up at that location. During the school year she would call me at all hours of the night and all weekend. i changed my phone number 5 times and it was unlisted but she would still get my number from the daughter of one of the cooks (without the mother's knowledge). She began acting beyond terrible in class when my now husband and I got engaged. She would leave me notes on my car, send me flowers, leave stuffed animals on my desk, etc. After about the tenth conference with her parents, who didn't see a problem with her behavior, BTW, I asked that she be removed from my classroom. She said that if they took her out of my class she would kill herself. I refused to teach the class with her in it so they removed her from the class.
The school finally let me get a restraining order against her that prevented her from coming on school grounds. She was placed on a mental health hold after she was arrested for bullying other students into leaving items for me and for also sending me threatening letters.
That was 10 years ago. 2 years ago the letters started at school again so I once again had to get a restraining order. Now that she is an adult the penalties are much worse.
Aren't you glad you asked, monkeyboy?
