Schizophrenia Forum - Concerned About Someone

Sorry if this is kind of long ... I have a lot on my mind at the moment and so kinda have difficulty expressing myself!

I used to run an anti-racist website where we used to allow opposing views, meaning we allowed racists to post. One of the people who joined was a girl about a year older than me. She seemed a nice enough person except that she was really obsessed with race and getting racist groups to accept her and believe she was white, despite the fact that she was obviously not going to be accepted by them because of her family history. I began speaking to her on aim in an effort to get her to change her mind, however I soon discovered that she has a lot more disturbing behaviour. When she was younger she used to be in a lot of trouble with the police and she tried to tell me how to make a bomb. She is also hysterically religious, not that there is anything wrong with thid as I am religious myself, but she tried to tell me that it was ok to do things to abortion clinics and believed she was on some kind of mission to stop immorality. She also can be quite reasonable (by her standards) some days and others not, but seems to have problems holding a conversation with someone, she will just completely change the subject out of nowhere, or log off or whatever. She is on medication but refusing to take it. I don't know what she has but I think it might be schizophrenia or schizotypal personality. She seems to forget or take no notice of what you say and she frequently asks the same questions to me almost all the time I tlak to her. However, she has met a man on the internet who is as racist as she is and who happens to be 39 years old, she is 18. She asks me all the time whether she should sleep with him and sometimes several times in the course of one of our conversations, she will ask whether it is ok to do thins like get into the back of the car with him, etc. She has not met this guy and she is being taken advantage of. I am no longer involved in the running of the site but I continue to talk to her, and it seems to me that her ideas about their relationship (he has told her all these lies which she believes) are delusional especially given the othe things which she is obsessed with and given the circumstances. She also has other delusions such as that there is a secret jewish soceity that controls the media and that white people are being "destroyed" by the jews brainwashing them, I am jewish and yet she continues to say these things to me all the time. She is also obessed by the thought of black people having sex with white people and constantly talks about how angry she is against all kinds of people, sometimes it will be racists, sometimes it will be blacks, sometimes it will be jews, sometimes it will be her family. Although she is a christian, she told me once she wanted to convert to islam. She has a strange way of talking, repeats herself a lot, uses very limited vocabulary and some people have said she might be autistic, but she writes far too simply for that and I thought that autistic people weren't normally nuts like this.

I am worried that this man who she is involved with will hurt her as he has a history of violence and writing about violent ideas, she has not told her parents about it and although I dont "know" her in real life I am one of the only people she regularly talks to and I would feel terribly responsible if something were to happen to her.

I wnated to know if anyone had ever come across someone like this before, whether she is schizophrenic or something else and whether there is anything that I could be doing to help?
