Ask HN: how do comparison websites prevent scraping?
I'm developing a web app not too dissimilar from a price/flights comparison one (nothing to do with travel though) and part of it is collecting lots of info not currently available in a single db (that's were the value really is).But then I wonder: how to I prevent people from getting all that data off my website (via some sort of scraping, intelligent or not)? I realise it's not worth it to...
