There is no technical way to prevent web scraping Every web request contains a browser signature, so-called User agent, and in theory, a web server can detect and reject non-human browser requests. However, modern scrapers can impersonate themselves as different browsers and bypass this check.

Can a website stop web scraping?
A good bot detection solution or anti-crawler protection solution will be able to identify visitor behavior that shows signs of web scraping in real time, and automatically block malicious bots before scraping attacks unravel while maintaining a smooth experience for real human users.
Can you prevent screen scraping?
Use Captchas if you suspect that your website is being accessed by a scraper. Captchas ("Completely Automated Test to Tell Computers and Humans apart") are very effective against stopping scrapers.
Can a website tell if you scrape it?
Technically, there's no way to programmatically determine if a page is being scraped. But, if your scraper becomes popular or you use it too heavily, the source may be able to detect scraping statistically. If you see one IP grab the same page or pages at the same time every day, you can make an educated guess.
How do you not get caught web scraping?
To avoid that, you can use proxies. A proxy server acts as a middleman - it sends requests to a website and retrieves the data for you. While doing so, it will mask your IP address on its own. Big web scraping projects require thousands of connection requests – you can't possibly do that from a single IP.
