Operators of public-facing websites are typically concerned about the unauthorized, technology-based extraction of large volumes of information from their sites, often by competitors or others in related businesses.  The practice, usually referred to as screen scraping, web harvesting, crawling or spidering, has been the subject of many questions and a fair amount of litigation over the last decade.

However, despite the litigation in this area, the state of the law on this issue remains somewhat unsettled: neither scrapers looking to access data on public-facing websites nor website operators seeking remedies against scrapers that violate their posted terms of use have very concrete answers as to what is permissible and what is not.

In the latest scraping dispute, the e-commerce site QVC objected to the Pinterest-like shopping aggregator Resultly’s scraping of QVC’s site for real-time pricing data.  In its complaint, QVC claimed that Resultly “excessively crawled” QVC’s retail site (purpotedly sending search requests to QVC’s website at rates ranging from 200-300 requests per minute to up to 36,000 requests per minute) causing a crash that wasn’t resolved for two days, resulting in lost sales.  (See QVC Inc. v. Resultly LLC, No. 14-06714 (E.D. Pa. filed Nov. 24, 2014)). The complaint alleges that the defendant disguised its web crawler to mask its source IP address and thus prevented QVC technicians from identifying the source of the requests and quickly repairing the problem.  QVC brought some of the causes of action often alleged in this type of case, including violations of the Computer Fraud and Abuse Act (CFAA), breach of contract (QVC’s website terms of use), unjust enrichment, tortious interference with prospective economic advantage, conversion and negligence and breach of contract.  Of these and other causes of action typically alleged in these situations, the breach of contract claim is often the clearest source of a remedy.
