The one that was closed was needing more and more moderator attention due to name calling. I suspect that someone, a mod or even a forum member, asked Jacob to take a look at it. If Jacob or the mods think that one of the posters (or more) is really looking for a fight, a thread is likely to get closed. It has never had anything to do with the longevity of a thread that simmers along without disruptive comments.
