Yeah kinda, but designed to actually be read :P

I was thinking it would contain the offending comment, a little message about it being flagged for not meeting community standards, then briefly list the community standards. A little word of encouragement and a button to show they've actually got the message- and off they go. I don't think it would need to be confrontational or make them actually agree to anything (since they might have good reason to disagree). But a gentle reminder about acceptable behavior could help new people get acclimated.
