"yes! you could even charge a small amount of money for that! most of the time i'd gladly pay a small amount instead of waiting several days for the scrape/api to finish!" And you'd be surprised at the number of sites that will happily sell you a dump of the data. It's just such a niche thing that site owners will rarely tell you on your site. As geeks we tend to assume that if something is not mentioned on a website as being for sale or available, then it must not be available. This is not true. Always ask!
