Google Safe Browsing: Prevent and Fix

One upstream blocklist (Google Safe Browsing) feeds Chrome, Brave, Safari, Firefox, and Edge. A flag there blocks the site in every browser at once. It is a classification of the public surface, not a hack — do not start by debugging code.

Quick check: is a site flagged?

# Replace the domain. Check apex AND www — they are scored separately.
curl -s "https://transparencyreport.google.com/transparencyreport/api/v3/safebrowsing/status?site=example.com"

Response is )]}' followed by [["sb.ssr", STATUS, bool, bool, bool, bool, bool, timestamp_ms, "site"]]:

• STATUS 1 + all false = clean.
• STATUS 2 + any true = flagged. The browser interstitial text tells the category: "trick you into revealing passwords" = deceptive/social-engineering; "install dangerous programs" = malware.

Prevention checklist (every new public web project)

1. No third-party trademarks in the domain. youtube-x.com, paypal-tool.io = brand + login form = automated phishing flag, and a trademark complaint risk. Use subdomains of a domain you own (tool.yourname.com).
