Google has largely solved the spam problem for end users. What I can't figure out is why platforms like Facebook and Twitter couldn't mark these sort of posts as, essentially, spam, by the same sort of rules and heuristics as email spam. Why can't they look at the metadata of verified troll-farm-generated clickbait/junk/spam/fake news, and make their own filters, and demote that content?
Simple. Because they're making money on the garbage. It's a misalignment of incentives. Until that is fixed, through reorganization or regulation, the problem will persist. They will only do enough to fight this -- both in terms of technology and public image -- so that it doesn't impact their bottom line(s).
