@TimStone I'd provide comments to the user, edits to the post where appropriate, and links to the relevant meta discussions with a summary of what they say. I've
done this in the past and I think our mods have done a good job of this so far. After a few exchanges it will be obvious that the user is not getting it or does not want to get it, and that's when it's time to ignore the user or suspend their account (depending on their behavior).
