Since you're here, can you comment on the problem of SEO spam and what DDG is doing about it? Just today I was looking for instructions on how to replace the cushions on my headphones. I typed into DDG the query "instructions to replace bose headphone pads" and it came up with pages and pages of links to SEO slop. The link to the actual Bose website containing accurate instructions was near the bottom of the second page of results.
