Well, I know a number of Rotorheads personally but I would never disclose publicly who they are. If people wish to remain anonymous, then I think that is their right. There are some who are open about their identity and other who just don't mind if they are recognised (like me!). Those who know me can easily work out who I am - if you see what I mean?
However, if you think you know who someone is, then it should best be done by PM, not publicly. There are those who don't wish to be identified and those who have a number of logins.
