AI companies exposed for mass acquisition of old books to obtain"Clean"Training materials

To avoid low-quality 'AI junk content', multiple AI companies are mass-purchasing secondhand books through intermediaries as high-quality training data sources. Reports say the relevant procurement scale ranges from a thousand to a million books, with no topic preference and regardless of price. This destructive scanning method is efficient, but may cause precious books to disappear permanently and trigger ethical disputes over the privatization of knowledge resources.
