There was a story on TechTV about four months ago that had to do with a man who was having problems with people getting into his system, He built a honeypot for collecting info on the hackers and to try to get their ISP to help stop them. I do not know if anything happened to him, but the info he collected was turned over to the FBI. as for scanning, was not illegal in itself, but posting the info is. I just wish I could remember the name of the story for the honeypot.

Thank you for your time.
