Get rid of it.
It has NO direction whatsoever.
I'm sorry, when page 340 is virtually indiscernible from page 140
(same people, same arguments, same pictures), its time for the thread to go.
No outsiders bother to read it anymore, its a unique microcosm of sorts.
Its post-whoring though, plain and simple.
I wouldn't be allowed to start a thread with a rival where we simply repeat subtle variations of the exact same content. Likewise, I wouldn't be allowed to post the same thing over and over in ANY other thread, even if it was slightly modified.
Why should ~10 members be allowed to reitterate the same old tired arguments and recycled pictures from a small archive consisting of only 30-40 boring photographs?
