Cause a bunch of people bothered to allow low quality pages to be indexed in their search engine? Just guessing.
Google can easily not show them considering they even show the fact it only has one post. They are the search engine and they can choose whether to include that page in the results.
As a searcher you should be able to spot the 1 Author results and just ignore them as well.
I just don't see the big deal. But all that said, to err on the side of caution we have noindexed all of these as well as any threads with less than 3 posts in them that are more than a year old. Knocked another 13,000 pages out. Doubt it's going to have an effect one way or another.
