I have a domain that had a previous owner. Google still shows thousands of their now nonexistant pages in the SERPs. I've modified my robots.txt to disallow all of those old pages (they were all conveniently in just a few /unique-folders/), but the old pages (which haven't existed for a couple of months) aren't going away, Google just isn't crawling them anymore. How do I remove thousands of non-existent pages from the SERPs? The one-at-a-time removal tool would be far beyond tedious.
