How to pick the right scam-check tool

Every scam starts with something you can paste: a link, an address, a handle, a screenshot, a phone number. The fastest path is to match the input to the scanner — paste a URL into the Website Checker, an EVM/BTC/SOL address into the Wallet Risk Checker, an X or Telegram handle into the Social Profile Scan. If you're not sure what kind of thing you have, paste it into the all-in-one Scam Checker and GACS will route it to the right engine automatically.

Why use GACS over generic scanners

  • Crypto-native. Drainer-script detection, fake-exchange fingerprints, pig-butchering broker patterns, honeypot simulation — signals the generalists never had to build.
  • Fresh. 100+ new community-confirmed scam entries every week from users in 50+ countries. Most scam domains are under 90 days old; GACS sees them within hours.
  • Transparent. Every verdict shows the exact signals behind it — no black-box score. You can argue with the reasoning instead of trusting a number.
  • Free forever. No paywall, no per-query limit. Funded by public donations, ad-free, with a published Free Forever Guarantee.

What to do if a tool flags something as a scam

  1. Do not enter any information and do not click anything else on the page.
  2. If you already entered a password, change it everywhere it was reused.
  3. If you sent money or signed a wallet transaction, follow the 15-minute panic guide for the recovery checklist.
  4. Report it so the next person who pastes the same thing sees the warning instantly.

Frequently asked questions

Are all GACS tools really free?

Yes. Every tool on this page is 100% free, no account required, no per-query limit for normal use. GACS is funded by public donations and runs ad-free. The same engines power the free browser extension and the public API.

Which tool should I use first?

If you have a URL, use the Website Checker. If it's a shortened or messenger link, use the Link Checker so it expands first. If it's a crypto address, use the Wallet Risk Checker. If you're not sure what kind of thing it is — a phone number, a handle, a screenshot — use the all-in-one Scam Checker or Ask the Detective.

Do I need to install anything?

No — every tool runs in your browser. There is an optional free browser extension that adds a one-click check on every page you visit, and a public API for developers, but you never need to install anything to use the tools on this page.

How is GACS different from Google Safe Browsing, VirusTotal, or ScamAdviser?

Google Safe Browsing catches well-known phishing. VirusTotal aggregates antivirus engines. ScamAdviser focuses on e-commerce. GACS adds what they miss: crypto-specific signals (drainer scripts, fake exchanges), live community reports in 50+ countries, AI text analysis of the page itself, and freshly-spun scam domains that the generalists haven't seen yet.

Can I report a scam I've found?

Yes — every tool result page has a 'report this' button, or you can go directly to /report. Reports are reviewed and added to the blacklist if confirmed. This is how the database stays fresh: 100+ new entries every week, contributed by users worldwide.
