California Case Sheds Light on Liability Issues from Use of Internet Bots to Gather Data

A recent California decision, Ticketmaster LLC v. Prestige Entmt Inc. (C.D.Cal 2018) pitted a website owner, Ticketmaster, against a company that used internet bots and other technical tricks to make massive purchases of tickets and then resell them for profit, something Ticketmaster strenuously wished to avoid.  On a motion to dismiss the complaint, the district court dismissed some claims by Ticketmaster but kept others. 

The decision teaches important lessons for companies whose websites contain large amounts of data or transactions to the public, but wish to keep competitors from extracting this data in mass amounts or engaging in mass transactions:

  • Adopt rigorous Terms of Use that prohibit bots, mass data extraction, or whatever other concerns one might have with competitors.
  • Include a license in the Terms of Use to all content and condition the license on adherence to the Terms of Use.
  •  Make rigorous use of technical measures (CAPTCHA, for example) to limit access to mass users, and prohibit circumvention in the Terms of Use.
  • Include liquidated damages provisions in the Terms of Use – but make sure they are reasonable both in the threshold where they kick in, and how they are calculated.
  • Most obviously, make sure that users must affirmatively agree to the Terms of Use – and record their assent to the Terms.
