2 reasons are most likely (based on my experience working on other forums):
1. Spammers bumping old topics. People start replying, then the spam post is removed but the conversation continues.
2. People doing a Google search, then signing up to respond to the post their search found even though it's an old topic.
We typically split these out to new topics to avoid confusion when they happen on our forums, but the QB forum software might not have that functionality.
