This reminds me of a true story...
This woman was using the Net for chatting and flirting, so on. She started talking to a guy who seemed to like everything she liked. She loved cats, so did he, she was a soppy romantic, he sent her virtual flowers, she liked men in uniforms, he was a fireman, etc,etc. However soon things got spooky when he started asking her who she had been emailing the night before, what she bought with the £40 she had taken out of her account the day before, etc. He had hacked into her computer, made easy because she had no firewalls, and was able to read her email messages, her bank account details, every site she visited (hence he knew she liked cats as she had visited cat websites), basically everything she used her pc for, he knew about. He hounded her for months before she found out what he was doing, by then he had her name, address, telephone number, friends addresses, etc. The police never did catch him.
So is there something you are not telling us here Simon?!!
