EFnet IRC Network Forum

Hi everyone,

I work for a company that will remain anonymous. I enforce EULA's and other compliance issues for this company. Recently we have had a person using internet relays and making phone calls posing as several of the owners and commiting identity theft. I was wondering if any of you could point me towards learning how to go about tracking down the origin of these calls. I do not know much about IRC or anything like that but I am having a hard time finding anyone to assist me or some sort of research I can do to learn how myself. Any help is greatly appreciated.

the phone company would have records of the calls, but they aren't going to give out that information without a warrant.
