That doesn't actually sound very different from my experience with major search engines beyond the first page. I've taken it as a bit of an law that the Internet outside of large centralized and/or moderated sites gets very fringe very quickly. Since the whole point of the search engine is to display noncommercial sites, users will inevitably face thousands of self-published blogs of varying beliefs, quality, and truthiness. As these fringe sites take up more domain names by total volume than mainstream platforms (there is only one Twitter, Facebook, et al.), I am not surprised at all that they seem to be even more voluminous here than on commercial search engines.
