Can you grab IPs of those who post on Friendster's Bulletin?

Question

An unknown officemate of mine had been using friendster to spread malicious news about my office friends. I find it too cowardly and I'd like to teach him a lesson. I'd like him to be fired from the company am working in. I have to find out who he/she is.

Answer 1

Your IT department could figure out who is visiting friendster (if they are visiting from an office PC) and get to the bottom of this. I doubt they'll take the time to do that though.

There is no way to get the IPs of people who have already posted comments.
