There used to be a bot rating bot on reddit that used those comments to see which bots where actually good. It was useful. I'm hoping someone will make the same on lemmy and go back retroactively to index old comments.

I think that on some bots it is meant as feedback on its performance but to have 10 users give the same feedback is kinda annoying. Maybe Lemmy can have a feature were humans can approve/disapprove bot performance that doesn't involve upvote/downvote. It would only be available to bot accounts in the site's UI. Could possibly expand it's functionality to something more useful. Or just use the voting system because it's already in place.
