[WikiEN-l] User responds to personal talk in three places at once

[Simon Blandford]

I just issued an NPA warning to a user on their talk page. They 
responded with a rant and posted the exchange on (1) their talk page, 
(2) my talk page and (3) an article discussion page.

I am sure it doesn't need to be in three places at once and I am tempted 
to delete the response from at least the article discussion page but 
this is a delicate situation and I don't really want to make a mistake 
here. Or do I post my response in the same three places? Or replace two 
of the places with links.

What is the "correct" response in this situation?

Thanks,
SimonB
