Commercial web scraping - is it stealing?

  • Aren't sites able to prevent this type of thing through a prominent terms of use link on every page? (Ticketmaster 2003, Cairo v. CrossMedia Services)

    Is it that this is still a legal gray area, or is it that big companies can roll over small companies and individuals?

  • There's a lot to be concerned about here for anyone who provides a data mining backed web application or service.

    At PatientsLikeMe patients are trading use of their information for free access to data analysis tools and social community.

  • It's almost always going to violate the site's TOS, so if you're a business that depends on regularly scraping sites without permission, prepare to change your business model or be sued. (eg. Octopart vs Mouser and Digikey)

  • So, when are we going to get a law making it illegal to violate robots.txt?
