Educate users, make policies visible by leaving comments
I consider this answer to be in agreement with mxyzplk's answer, but I feel like the rationale here is different in a way that is important in the discussion.
Aside from the obvious things we should already be doing (not answering in the comments, flagging answers in comments aggressively) I do have a proposal that I think might be useful.
I think that we should try to always leave a comment when see an answer in the comments (after flagging/deleting). I know we do do this, but I don't think we do it enough.
The reason I say this something we should be doing more is that as a new user this was exactly the way I learned how to behave. Seeing "comments are not for extended discussion" and "don't comment in the answers" comments in a lot of places is what helped me learn what is accepted in the community without having to make those mistakes myself first. It makes sense that this could be the case for other users as well.
Additionally, if the comment tags the person, they know that their comment was removed and why and hopefully won't do it again. This is helpful in cases where the person just leaves a comment then never reads the question again.
And, to be clear, this is something that every person in the community that has the rep to comment can and should be doing. This is not the sole responsibility of diamond moderators.
tl;dr When you (yes you) see an answer in the comments, flag it then comment saying that it goes against our policy. Doing so should create a greater awareness of the policy for new and experienced users alike.
This answer was spawned from my answer to a previous question (one of the answers that actually inspired this question): How is the community doing? [2018]
