I can see you Jeff! 
With regards to such notices, we would almost certainly not use them for any kind of user-moderation because we prefer to avoid publicly embarrassing (or chastising) a user if at all possible - only dealing with user issues more publicly if we have been left with little choice (for instance, by their behaviour or conduct increasingly affecting more and more people on the forum).
If those notices could only be seen by the creator of that post, we could use them in some instances so long as we could make obvious that only they can see it.
Why do we take this path? Because people hate being moderated and being ‘shamed’ publicly even more - it can be infuriating (and somewhat disrespectful - if someone has made a genuine mistake they shouldn’t be made to feel like an idiot in front of the whole community). Offending users like this can create huge problems further down the line - if they take umbrage they will never forget, and it will be compound future issues, which could lead to inter-community issues or them falling out with moderators (which unfortunately never ends well). At worst they could leave or get banned and carry out more malicious attacks. It is just not worth it, particularly if you were once reasonably confident they were a genuine user.
I agree - I just think at the moment the tools seem to reflect how moderation was traditionally carried out (with some improvements of course) but I think there’s probably a much better way (just like you all at DC have demonstrated for other areas of forum software)… we just need to work out what that better path is.
It’s a huge topic, but I think the main thing that requires our focus right now is making moderation as palatable as possible - while - not burdening the mod team.
Unfortunately I don’t have the time to go into greater detail atm, but would love to chat about this more in the new year perhaps?
