Since you are handing out free advice, is it normally considered polite or helpful here to accuse people of using fake accounts? Is assuming that a person speaking with confidence about a topic may have some direct knowledge of that topic somehow rude or against the rules?
If you're speaking confidently on behalf of the person that I was responding to, are you sure that you reflect their opinion faithfully? If the GP wanted to say "I refuse to give more details about the fund due to the phrasing of your request for details," surely they could have typed that themselves.
Namaste!
