I don’t have enough information to know what might be wrong with her. She may or may not be mentally ill. She might be playacting as part of her scam.
There’s little that you can do in this situation except inform the police. You may not know her name, but you do know about her website. The police can investigate further, should they deem it necessary.
After you report her to the police, you will have done all that you can. It’s best to keep your distance. Don’t interact with her in any way. Report her to the police and then leave her alone. If you have proof of her wrongdoings then, once again, report her to the police. If you have no proof, then you must completely leave her alone. You describe her as being a danger. Why would you want danger to be in your life? Stay away from danger. If you have trouble with her intrusion into your thoughts, then you should find a therapist to help you to forget her. Please take care.
