Ethics and authorization#

OSINT collection law and ethics differ by jurisdiction. The enabling discipline at Web Scraping and the authorization guidance at OPSEC should be read before running tools at scale. Personal data (PII) is governed by GDPR in the EU, CCPA in California, similar regimes elsewhere, “publicly available” does not mean “free to collect, store, and share.”
