Before we begin, it's essential to understand that data extraction and web scraping are legal gray areas. For some, this is highly immoral, if not outright illegal, so pay attention to what you're scraping and how you're using it. Scraping personal data, gathering information without permission, or copyrighted data (among other things) may be illegal. So make sure you're careful about what you get and what you do with it once you have it. This information can make a big difference for your business, but if you're not using it correctly, it could cause you problems.
