What GACS checks
- Websites & domains — phishing sites, fake exchanges, wallet drainers, typo-squats. Signals: WHOIS age, SSL posture, blacklist hits, learned phishing patterns.
- Crypto wallets — on-chain history, drainer heuristics, mixer proximity, reports across CryptoScamDB, community submissions, and confirmed rug-pull registries.
- Social handles (X, TikTok, Instagram, Telegram, Facebook, YouTube) — impersonation similarity, account age, follower-velocity anomalies, cross-platform scam fingerprints.
- Phone numbers & emails — robocall registries, recovery-scam pattern matching, disposable-domain checks.
- Messages & DMs — paste a suspicious message to detect pig-butchering, recovery-scam, and support-impersonation scripts.
How the scanner works
Every scan runs a layered pipeline: identifier normalization, blacklist match, learned fraud-pattern match, per-category enrichment (WHOIS, on-chain, follower graph), and a weighted risk score. Output is a verdict (Safe / Caution / Danger), the specific evidence behind it, and — when confirmed — a permanent public warning at gacs.app/scam/<slug> so the next person Googling that identifier finds the warning first. Full technical detail: How GACS works.
What you get from a free account
- Save every scan to your Shield so you can revisit verdicts and share them with family.
- Monitor handles, wallets, and domains — get emailed the moment a verdict flips to Danger.
- Add family members to your watchlist so you're alerted if someone contacts them from a known scam identifier.
- Pin evidence, submit reports, and cite the resulting public page in disputes, chargebacks, or law-enforcement reports.
How GACS compares to other checkers
Most "scam checkers" are either browser-extension trust ratings (site-only, no wallet or social coverage) or paid recovery services that charge victims after the fact. GACS covers every identifier type in one place, publishes a citable warning page for every confirmed scam, and stays free for individuals forever — see the guarantee.

Frequently asked questions
Everything people ask before their first scan. Answers match the FAQ schema Google reads for rich results.
›Is GACS really free?
Yes. Every scan — websites, wallets, phone numbers, emails, and social handles — is free and ad-free for individuals, with no signup required. Paid tiers only cover family monitoring and pro-level features; see the free and ad-free Guarantee for the full commitment.
›Do I need to create an account to scan something?
No. Paste any URL, wallet, phone number, or handle and you'll get a Safe / Caution / Danger verdict in under 30 seconds without signing in. An account is only needed if you want to save scans, monitor identifiers, or get emailed when a verdict flips to Danger.
›What can GACS check?
Websites and domains, crypto wallets (EVM, Bitcoin, Solana, and more), social handles on X, TikTok, Instagram, Telegram, Facebook, and YouTube, phone numbers, email addresses, and pasted messages or DMs for scam-script patterns.
›How does GACS decide if something is a scam?
Each scan runs a layered pipeline: identifier normalization, blacklist match against 410,000+ confirmed scams, learned fraud-pattern matching, per-category enrichment (WHOIS age, SSL posture, on-chain history, follower-graph anomalies), and a weighted risk score. The verdict is returned with the exact evidence behind it so you can verify it yourself.
›How accurate are the verdicts?
Confirmed-scam matches are deterministic — the identifier appears in a curated blacklist or has been reported multiple times. Caution verdicts are probabilistic and always include the specific signals that triggered them (domain age, mixer proximity, impersonation similarity) so you can judge the evidence rather than trust a black-box score.
›Is GACS anonymous? What data do you keep?
Scans are anonymous by default. GACS does not resell data, does not run advertising trackers, and does not require a wallet connection to check a wallet address. Signed-in users control what they save; anonymous scans are used only in aggregate to improve detection.
›How is GACS different from browser scam-warning extensions?
Browser extensions only cover websites and rely on domain-level trust scores. GACS covers websites, wallets, social handles, phone numbers, emails, and messages in one place, publishes a citable public warning page for every confirmed scam, and stays free for individuals — so victims can link the page in disputes, chargebacks, or law-enforcement reports.
›Who runs GACS and how is it funded?
GACS (Global Anti-Crime & Safety) is an independent public-safety utility. The founder story, funding model, and organizational details live on the About page; this page focuses on what the tool does.
