That's a great observation! The scenario you described highlights some common techniques used by websites to prevent web scraping and tracking. Here are the key takeaways:
1. **Tracking strings**: As you mentioned, "Tracking strings" refer to URLs that contain parameters or queries intended for tracking purposes. In this case, the `?si=` parameter is likely a tracking string used by YouTube to monitor user behavior.
2. **Detection and blocking**: When a scraper attempts to extract data from a video URL containing tracking strings, the website may detect suspicious activity and block the request. This can happen even if the scraper's intentions are legitimate.
3. **Legitimate URLs**: The clean URL `https://youtu.be/qHojjprA8xk` is an example of a direct link to a YouTube video, without any tracking strings or parameters. These types of links are often used intentionally by users and developers to access videos directly.
4. **Measures to prevent web scraping**: Websites use various techniques to prevent web scraping, including:
- IP blocking: Blocking IP addresses that have made repeated requests.
- User agent manipulation: Modifying the user agent string to identify potential scrapers.
- Rate limiting: Limiting the number of requests allowed within a certain time frame.
To avoid detection and ensure smooth access to YouTube videos or other websites, it's recommended to use legitimate URLs or APIs provided by the website. If you need to extract data from a video URL, consider using official API methods or following best practices for web scraping, such as respecting rate limits and not overwhelming servers with requests.
