mattwnz: Maybe preventing new posters from starting a new thread, unless they have made 5 posts in existing threads, could be an idea to stop it occurring. This is what some forums do to stop this, and to also stop spammers.
Maybe something like that if it got out of hand, but personally I don't think it's a frequent enough problem to warrant such a change. Plus, then you would have to police them simply dumping 5 random pointless posts (simply saying "I agree" or similar) in other threads to get over the line.
The thread in question was quite funny when It started. It read kind of like a cross between the Monty Python Dead Parrot Sketch (with the OP seemingly the only one who didn't realise the parrot/topic was dead) and a McGillicuddy Serious political rally. But then it got circular and tedious, and I gave up on reading it.
I think the resolution was the correct one.
