A long-form romance + investment scam. Strangers build trust over weeks, then push you toward a fake investment or crypto platform. The money looks real until you try to withdraw.
They contact you on dating apps, WhatsApp, LinkedIn, Telegram. They show fake profits, fake KYC, and fake support agents. They isolate you from friends who would call it out.
Free scanners for messages, wallets, phone numbers and URLs. Real-time alerts. Plain-language education. A scam analyzer that explains what felt wrong — so you trust your gut next time.
Fraud is a public-safety problem. We never take deposits, never connect to your wallet, never run ads, never track you. The tool stays free so the most vulnerable people can use it.
Yes. GACS is 100% free with no ads, no third-party trackers, no deposits and no wallet access required. We do keep first-party analytics so we can measure what's working — we never sell data.
Open the Social Shield on the homepage. The Social Profile Scan tab lets you enter any username, handle, or profile URL to check for impersonation patterns and scam signals. The Scan My Following tab audits who you follow on X for hidden impersonator or scam accounts.
A long-con romance/investment scam where the victim is groomed over weeks before being directed to a fake investment platform. GACS provides specific tooling and warnings for this pattern.
GACS does not recover funds and warns against any service that promises to. We provide a step-by-step Panic Guide and direct reporting links to the right authorities for your jurisdiction.
Anonymous scans are not tied to an account and are not retained beyond short-term abuse-prevention logs. If you create a free account, your scan history is saved only to your account so we can re-alert you when a verdict changes. We never sell data and we don't run third-party ad trackers.
GACS combines our public blacklist of 80,000+ confirmed scams, live community reports, on-chain wallet history, domain and WHOIS signals, social-account age and impersonation patterns, and known scam-template matches. Each verdict lists the specific signals that triggered it so you can audit the result.
Use the Report a Scam page to submit a URL, wallet, handle, or message with optional evidence. Reports are reviewed and, once corroborated, added to the public scam database so future scans warn other users automatically.
GACS is a nonprofit anti-fraud public utility. We're funded by donations and grants — not by ads, affiliate fees, or selling user data — so a verdict is never influenced by who pays. This is also why we will never ask for payment, seed phrases, or wallet access.
20+ languages and major world currencies — auto-detected from your region, override anytime from the header.
Open the Panic Guide for step-by-step actions to freeze accounts and limit damage, then file with the right authority in your country — official channels, evidence checklist included.
