fraud detection

Practical Linux/Bash playbook to protect your identity in the AI era: strip metadata and downscale media; fence off crawlers with robots.txt and X‑Robots‑Tag; verify authorship via GPG/SSH signatures; lock accounts with FIDO2/U2F for sudo and SSH; scan repos for PII and secrets with ripgrep; and use Tor for anonymous research—so you leak less, get scraped less, and can prove the real you.
