You would have assume that he isn't in the Chairman's Lounge as their own code of conduct states:
Airlineratings.com must disclose material conflicts of interest that could be seen to affect the accuracy, fairness or independence of their reports.
I can't see how you could be in charge of such a website and be in an invitation only airline lounge.
Unless there is some legal ruling that excludes being in such things doesnt constitute a conflict of interest.
