Is scraping websites legal?
There is no simple answer to this question as it depends on a number of factors, including the country in which you are scraping the website, the purpose of the scraping, and the specific website being scraped. In general, however, scraping websites is likely to be considered legal in most cases.
For example, if you are scraping a website for personal use in order to create a database of information for your own reference, this is unlikely to be considered illegal.
