This has been an ongoing problem for me, though not violent. In my case, they'd stalk my friends or family and send them messages. The description of the female stalker was dead-on. If it's anything direct, they use ways to make it look like anyone. Be careful when you hand out your information about where you live like the city, university, college, etc. Recently did that with a tinder match (university) and shit got really weird past few days, like strangers asking me for personal details, or making very specific references to my past actions years ago on campus. The stalkers can really try to ruin your life. Had deactivated social media, except for an account my close friends and family only know. It's been better since. There has been way more identifiable things that have been going on the past few years, but I'd rather leave em out of the web, and just keep gathering the incidents. Take read in case this happens to you.

Most people scoff at the notion of a female stalker. “Oh, you poor guy! Some woman wants to have sex with you!” they will say with sarcasm. But let me tell you, these nut jobs can take over your life, and make you feel very unsafe. Your guard will constantly be up, because whilst it is easy for a man to physically defend himself against a woman, this is only true if he sees her coming. At best they are merely an annoyance, but no matter what they absolutely will not take no for an answer.

Not always sex, but ruining your life trying to make you feel "lower" than them when doing anything positive for your future.

Female stalkers were predominantly single, heterosexual, educated individuals in their mid-30s who had pursued their victims for more than a year. Major mental disorder and personality disorder were suggested, especially borderline personality disorder. They usually threatened violence, and if they did threaten, were more likely to be violent. Frequency of interpersonal violence was 25 percent, but there was limited use of weapons, and injuries were minor. Stalking victims were most likely to be slightly older male acquaintances; but if the victim was a prior sexual intimate of the female stalker, her risk of being violent toward him exceeded 50 percent. Unlike male stalkers who often pursue their victims to restore intimacy, these female stalkers often pursued their victims to establish intimacy. Common emotions and motivations included anger, obsessional thoughts, rage at abandonment, loneliness, dependency, jealousy, and perceived betrayal.

Literally dead-on.
