Well after developing my script some more it revealed some 1,000 pages of my forum had less than 30 words in the full thread and a whopping 4,000 had 2 or less words in the title. This equates to 25% of the total site.
Rewriting 5,000 pages was not an option and as Google wasn't sending any traffic to them and on browsing them they do nothing for the user they have gone. Time will tell.
