I have a stalker who has been posting screenshots of my posts. She has an arrest history for violence. If you are reading this post anywhere except on http://www.websleuths.com please exercise caution because I have reason to suspect that she is a danger to others.

Wikipedia gives a better understanding of what cyber stalking is.
A number of key factors have been identified:
Many cyberstalkers try to damage the reputation of their victim and turn other people against them. They post false information about them on websites. They may set up their own websites, blogs or user pages for this purpose. They post allegations about the victim to newsgroups, chat rooms or other sites that allow public contributions, such as Wikipedia or Amazon.com.
Attempts to gather information about the victim.
Cyberstalkers may approach their victim’s friends, family and work colleagues to obtain personal information. They may advertise for information on the Internet, or hire a private detective.
Monitoring their target’s online activities and attempting to trace their IP address in an effort to gather more information about their victims. 
Encouraging others to harass the victim.
Many cyberstalkers try to involve third parties in the harassment. They may claim the victim has harmed the stalker or his/her family in some way, or may post the victim’s name and telephone number in order to encourage others to join the pursuit.
The cyberstalker will claim that the victim is harassing him/her. Bocij writes that this phenomenon has been noted in a number of well-known cases.
With the number of sock puppets used JUST on this blog, it is easy for all these points to occur and appear to be coming from different people. This is why all these sock puppets say “we” and “us”. These sock puppets are his groupies, his lynch mob, his defense, his ego, his back up, his wing men…
When he needs any of those, a new sock puppet comes out. Problem is, I see his hand in his sock puppets, and he’s NOT happy about it.
He knows I’m a woman. He knows where I live. He knows my family’s names.
Ask yourself, why would anyone even be interested in my identity? Someone I’ve named publicly as my person of interest, maybe? Charles Peter Hackett?
