    Some sites block IP addresses when they want to stop or ban a particular web scraper from extracting their data on a site. This is the typical occurrence in this game. It often ween when the site experiences multiple requests coming from a single IP address. Therefore, a target site can decide to ban the IP address or restrict access, stopping your scraping action.

    Thus, you will be prompted to use the proxies. Integrated the relevant proxies into your scrapers and evade the restrictions or blocks. When unethical scraping is detected, the site flags and blocks you. So, be smart and get the needed resources to be on the right side to achieve your target.

Thus, you need to amend the design of the scraper or adjust it. Meaning, that your scraper will also need to get constant maintenance. So consider setting up continuous integration to do a test often.
