If the person seems unresponsive to polite guidance on making accurate/reasonable identifications, and these are their own observations, I would probably lean toward tagging in or privately messaging other users who can help and let the situation get resolved through the community identification system.
If a person is making intentional misidentifications on other people’s observations, it needs to be addressed more firmly, potentially by a curator or staff.
As far as “he…hid my comments” – the only people who can hide comments are curators and site staff.
