I was looking at my google webmaster tools account and it lists several pages as crawl error 500. The bizzare thing is that the pages don't technically exist. I don't have these folders and I can't imagine I have these paths linked to anywhere on my site. Google seems to be indexing fake blog paths. It must be a bug somewhere. Here are some examples. The links usually work, but they don't make sense. They aren't the right paths.
