Throwing dozens of articles, social media posts and why not even videos. Hallucinations really don't matter at scale. And enough content is already generating enough views to make it somewhat viable strategy.
I think for some niches, the former can for a brief period precede the latter. But eventually the market catches up and roots out that which lacks actual value.
More concretely, I suspect the advertising apparatus is going to increasingly devalue unattributed content online, favouring curated platforms and eventually resembling a more hands on media distribution with human platform relationships (where media == the actual medium of distribution not content).
That is already a thing, where for example an instagrammer promoting your product is more valuable than the automated ad-network on instagram itself.
At which point, hopefully, automated content and spam loses legitimacy and value as ad-media.
