Indeed. I recently noticed this while relying on DDG for documentation for Common Lisp, a language I still learning. The top-ranking site for any Common Lisp function was an SEO scam site, where clearly someone had hired freelancers to take preexisting CLisp documentation and rewrite it – in poor-quality English – until it would no longer be detectable as copyright violation, then loaded it with ads.
(I just checked and this copycat documentation site has, thankfully, now been pushed down a bit in DDG results.)
Note that as I quite recently learned DDG has support for a bunch of bang-commands listed at [1]. There are a bunch of them for documentation sites for all kinds of programming languages, including a couple for lisp it seems like.
