Business dangers from scraping / automation are basically of two types:

• archival record for proof mostly for legal prosecution and contract negotiation. There’s a lot of really bad shit going on on Chinese web despite the great firewall of China and you can hide it in plain sight if it’s ephemeral. So if I sell illegal goods but it’s not archived ever no one can really prosecute me. Gray/black markets players in China just rebrand every month and get away with everything.
• real time data for price/trend competition. Prices and trends move incredibly fast in China, people in the west don’t even understand how far ahead chinese e-commerce is, Amazon is like 10 years behind. So all that scraped info is incredibly valuable for chasing capitalism.
