Putting my Mod had on for just a moment, we try not to interfere with what folks are posting, unless the posts are contrary to forum policies, or just blatantly nasty. That Freedom of Speech, business, you know.
Besides, if we closed all the pointless threads, we wouldn't have half so much fun.
Now removing my Mod had, I'll observe that threads tend to die on their own when folks stop reading and responding to them.
