Why would you even have the real names of users? If they willfully filled out their 'real' names in a 'real name' field then just go ahead on cooperate, obviously they don't care... Otherwise you can't give up what you don't have... I'd send a notarized letter to whatever address you need to respond to saying "As is customary practice for web forums of this nature we do not collect the real names of our users and are therefore unable to supply you with the requested information. If we can be of any further service please do not hesitate to contact us again." I also read somewhere that you can legally charge a fee for looking up said information that would have to be paid by the person requesting the info so if you do end up needing to do this document your time spent and bill them for your time.
