AG published a form for reporting fake comments: https://ag.ny.gov/fakecomments-form
I have little reason to believe the person who left this comment is real or rather if the person is real, I doubt they actually left the response. However I don't think I should file it on their behalf in case I'm wrong.
I guess if they want the information, I'd pass it onto his staff and let him and his staff do the research to determine it's authenticity although that seems like a lot of work to authenticate one person.
