I have not had a serious Stalker myself (I've had a few people who would follow me around certain boards trying to provoke me to get me banned, but thats more annoying than "scary") but in college I had to assist a couple female friends and acquaintances to spread the word to a couple young men to mind their distance. One guy who was an Ex-boyfriend/ One night stand would sit in a stairway 8 ft. across from my one friends apartment for hours so he could interact with her, and rush into elevators to be with her. It got to the point I had to go and physically tell him to move along, once I found that he didn't live on he floor and had no business to be there. That was pretty serious, but not the worst stalking issue I was involved with.
The other main instance from College was one of my friends broke up with her boyfriend, and his roommate (who she thought was a friend) "Date-raped" her (they started making out, she stopped or said she wanted to stop, he held her down to keep going till he finished) one night when she came back to get her stuff, and then would do passive aggressive stalking to keep her quiet about it since he had a girlfriend already. I had my doubts about it since the guy didn't seem directly threatening (i.e. I never caught him doing it) and she put herself into bad situations constantly, till I walked into the break room at school and heard him telling her her to stop telling people what happened "to remember that she started dick teasing him, and he can make her disappear because of his family connections". That's all I needed to hear to turn the tables, even though when I tried to get school officials involved they said it was a "he said, she said" issues, and she should have contacted the police or them immediately. But he eventually moved away after his girlfriend got wind of the threats of violence, and myself and three other guys made his life a little "difficult" to be anywhere near her. Last I heard the loser his dad got wind of him throwing around the Family Connections, and cut him off. He got addicted to hard drugs and just "vanished" himself.
Oh College...
There was a recent issue with my girlfriend of 12 years being Cyber-stalked by a former co-worker who became infatuated with her, but that is a whole other story.
