I don't think there's a way to limit comments to registered users, but you can limit *all* editing to registered users if there's a strong need for it (and that would include comments). Discuss the situation with your community first to see if they agree it's a necessary step (keeping in mind that if you limit editing to registered users, it makes it harder for new people to start contributing). If you all agree, send us a link to that conversation via Special:Contact with examples of where you're seeing problems, and we'll review the situation further. Best of luck!
