The $60.5 million judgment that craigslist obtained in April 2017 against RadPad, a third party that collected data from craigslist's site through automated means, highlights some of the issues faced by entities that collect – or engage others to collect – data through automated means for commercial purposes. The judgment was based on various claims relating to RadPad’s use of sophisticated techniques to evade detection and harvest content from craigslist’s site, as well as distribution of unsolicited commercial emails to craigslist users to market RadPad’s own apartment rental listing service.
