How do I send feedback, and where do I report something?

They are two different things. The Feedback board is for ideas and problems with the app itself: post one, vote on what others have suggested, and follow it through In Review, Planned, In Progress and Completed — the Progress page shows what is being worked on and the Changelog what has shipped. To report a companion, a person, a post, a comment or something an AI said, use Report where you found it rather than the board.
