Generally the best option is to just remove the tag, but to conform to WP:BITE, if a clearly inexperienced user is trying to do their best by tagging all the articles in the world, we give them a nudge with that template. Of course, I've never seen anyone use it, its just there in case its ever needed.
I think I could have avoided a lot of the fallout that occured had I used something like this. Well, maybe, hard to say.
But I do have a suggestion: could you make the template smaller? It's HUGE! I'd actually feel bad putting this on someone's talk page. Perhaps something that is much smaller and links to a page that has the content within?
