Seeking way to find harrasing people

Hi there,

I keep getting really nasty people using my contact page to harass me & call me names.

We added on the plug-in that tracks the URLs they go thru & their IP address.

While the IP Address is useful, the URLs thing doesn’t really work. It just shows favicons, the theme of the blog itself etc.

Is there any other plugin that will help me to either prevent this (not willing to take down the contact page) or track them if they do act this way?

Thanks

Michelle
