Legal issues
United States
In the United States, there exists three most commonly legal claims related to web scraping: compilation copyright infringement, violation of the Computer Fraud and Abuse Act (CFAA), and electronic trespass to chattel claims. For example, the users of "scraping tools" may violate the electronic trespass to chattel claims. One of the well-known cases is Intel Corp. v. Hamidi, in which the US court decided that the computer context was not included in the common law trespass claims. However, the three legal claims have been changed doctrinally, and it is uncertain whether the claims will still exist in the future. For instance, the applicability of the CFAA has been narrowed due to the technical similarities between web scraping and web browsing. In the case of EF Cultural Travel BV v. Zefer Corp., the court declined to apply CFAA since EF failed to meet the standard for "damage".
European Union
By the Article 14 of the EU's General Data Protection Regulation (GDPR), data controllers are obligated to inform individuals before processing personal data. In the case of Bisnode vs. Polish Supervisory Authority, Bisnode obtained personal data from the government public register of business activity, and the data were used for business purpose. However, Bisnode only obtained email addresses for some of the people, so the mail notifications were only sent to those individuals. Instead of directly informing other people, Bisnode simply posted a notice on its website, and thus it failed to comply with the GDPR's Article 14 obligations.
Australia
In Australia, address‑harvesting software and harvested‑address lists must not be supplied, acquired, or used under the Spam Act 2003. The Spam Act also requires all marketing emails to be sent with the consent of the recipients, and all emails must include an opt-out facility. The company behind the GraysOnline shopping websites was fined after sending emails that breached the Spam Act. GraysOnline sent messages without an option for recipients to opt-out of receiving further emails, and it sent emails to people who had previously withdrawn their consent from receiving Grays' emails.
China
