The report from TechCrunch AI highlights a significant second-order effect of generative AI's proliferation: the commoditization of spam. While Reddit's claimed 20% reduction in spam exposure is a positive metric, the deeper concern is the structural shift this represents. Platforms are now locked into an expensive, perpetual technological arms race where the cost of defense scales with the falling cost of offense.
This dynamic arguably benefits large, well-resourced platforms while potentially squeezing smaller communities and forums that lack the capital for sophisticated AI moderation tooling. The long-term question is whether this cycle can be sustained or if it will fundamentally alter the economics and openness of online discourse.
