Another example of the staleness: On January 12th I discovered a domain setting their CNAME to mine, and getting indexed with my content. I set up 301 redirects that same week, to force requests for their domain to my canonical. Google STILL has their domain indexed with my content. Another site that was using my logo was taken down in mid January (serving 404 for 6+ weeks), but is still indexed. Granted, I could submit the latter to the url removal tool, but I shouldn't have to.
