I can’t find the topic you are referring to exactly but in this one the question about giving own whereabouts was answered in the next post but that aside, the topic is one of wide interest across France and the locale was not directly specific to the matter under discussion from what I can remember of it (with a quick scan of the posts).
I’m not entirely sure in that case that I follow your point…
Sometime people leave the site for all sorts of reason (or move area) and including a locale with their username could, over time, become less relevant.
