It is Unrealistic to ask / expect people to use their real ID info in a forum (yes, my name is actually Andrew Scott), however it is to be expected that people will feel upset and mislead if someone seems to be misrepresenting themselves in any way.

The anonymity of the web allows us to be less concerned about offending others (and any consequences) than we would fact to face and probably encourages us to say more "brash" comments that in public.
