Normally I see the possibility that simple facts will take care of the issue. I missed it, and went to general principles. Glad that you used the "fact" approach
BigA answered the question. I, like you, am in the position of sort of wishing I knew what prompted the response. I can guess, in some instances, by noting responses. And I wrote a post in Spanish, a few days ago, that seems to have caused almost ten PMA messages in 5 minutes, once. It's my personal record.
I was warning some guy who had already given away his credit card info. All I said was informative stuff, about changing credit card and checking account numbers. Geez, were those shills nasty. Well, I have to assume so, because I just saw the PMA messages.
