According to DeepLearningAI, websites are increasingly deploying advanced methods such as decoys, anti-crawling blockers, and paywalls to limit AI crawlers from accessing their data (source: DeepLearningAI, The Batch). This shift marks a significant change in the AI industry, as open web data becomes less accessible for training large language models and generative AI systems. Businesses relying on web-scraped data now face new operational risks and may need to seek alternative data acquisition strategies. The trend signals a growing 'shadow war' between content owners and AI developers, reshaping the landscape for AI training datasets and pushing companies to invest in proprietary data or licensing agreements to maintain competitive advantages.
