I have been trying to learn how to scrape list off websites. One of the ways that I use to do this is "WhoIs". Is there any other ways to scrape that information? Also, this is an interesting Challenge that I have not been able to solve. When someone post something (i.e. a post on craigslist), there is a special "email" that craigslist use to cover up the real person's email. Is there a way to extract the real person's email on a craigslist post?
