I'm scratching my head over this: I don't understand why it's important for anyone's true name or identity to be established here?

Unless someone is selling something (like a doctor, lawyer, investment counselor, purveyor of sports betting information, teacher of dice control) why is it important what their name really is?

What is most important is what information they are providing.

I'm going to repeat that: what is most important is what information they are providing.
