Ask HN: What’s the legality of web scraping?
The rule of thumb seems to be:<p>- If the website offers the data publicly (without authentication), it&#x27;s free to scrape.<p>- If the data isn&#x27;t protected by copyright or trademark, (e.g. public data, such as an address of a house), it&#x27;s free to reuse.<p>- If you use the data to compete with a big company, they will sue you regardless.<p>Court resolutions will vary on the court and judge.
