Yes, web scraping is legal in Montana if conducted within federal and state legal boundaries, but compliance with data protection and anti-hacking statutes remains critical. Montana lacks state-specific web scraping laws, deferring to federal frameworks like the CFAA and CCPA, while local courts may scrutinize unauthorized data extraction under tort or contract theories.
Key Regulations for Web Scraping in Montana
- Computer Fraud and Abuse Act (CFAA): Prohibits accessing computer systems without authorization or exceeding permitted access, which may apply if scraping circumvents technical barriers like CAPTCHAs or login walls.
- Montana’s Data Privacy Laws: Align with the CCPA’s progeny; scraping personal data without consent risks violations under the Montana Consumer Data Privacy Act (effective 2026), which mandates transparency and consumer opt-out rights.
- Contractual Restrictions: Terms of Service (ToS) violations may trigger claims under Montana’s common law of contracts, as courts have enforced anti-scraping clauses in prior rulings (e.g., eBay v. Bidder’s Edge analogies).
Practical Compliance Steps
- Respect Robots.txt: Montana courts have cited adherence to robots.txt as evidence of good faith, though non-compliance does not automatically confer liability.
- Avoid Personal Data: Scraping PII without a permissible purpose under Montana’s 2026 privacy statute may result in enforcement by the Attorney General’s Consumer Protection Division.
- Rate Limiting: Aggressive scraping may trigger CFAA claims if deemed a “denial-of-service” attack, per Montana’s interpretation of unauthorized access.
