Web scraping is a controversial topic, with one group saying it is immoral while others feel it is okay. The legality of web scraping will depend on the nature of the content being scraped and the policy of the target web page.  Generally, scraping data with personal information such as addresses and financial details is considered illegal. Before you scrap for data, check if the site you are targeting has any guidelines. Always ensure that you don’t scrap that data that is not publicly available.
