> I think ultimately unless they're whitelisting sites (like SO) there is no way to algorithmically differentiate between blogspam and genuinely useful tech blogs It has always been utterly mindblowing that apparently not a single person with power in the entire chain of command at Google has ever recognized that websites showing exact replicas of content from the very small list of extremely famous moderated content generators like Stack Overflow should just be blackholed. The number of legitimate Stack Overflows (the genre of legitimate content producers, not the specific domain) is very small. The list could be successfully curated manually by a troglodyte. Like, FFS, give google engineers a button they can click to mark a site as crap. They use the internet too and there are literally tens of thousands of them googling to find things on stack overflow all day every day. All they need is a "this site is an SEO scam" button. Not doing this speaks directly to either malice or incompetence (personally I think both), because it's not a super obscure problem that nobody inside google has ever encountered before.
