What is GACS.app?

GACS.app — short for the Global Anti-Scam Coordination System — is a free, anonymous, independent public-safety utility that helps anyone on the internet detect social-media impersonators, scam crypto wallets, fraudulent websites, and AI-driven recovery scams in about 30 seconds. No account, no payment, no data stored.

Our mission

Online fraud now costs individuals an estimated $1+ trillion globally each year, and platforms catch only a fraction of it before victims send money. GACS exists to make scam detection a basic public utility — as universal as a search engine and as fast as a spell-checker — so the people most at risk are not the ones least able to afford protection.

Our purpose

GACS turns the messy, expert-only work of fraud analysis — checking account age, follower authenticity, bio red flags, wallet history, domain age, SSL trust, and cross-platform impersonation patterns — into a single paste-and-scan experience. The output is a clear verdict, the supporting evidence, and a permanent public warning page if the entity is confirmed to be a scam. The goal is simple: prevent the next victim before money moves.

Who GACS helps

  • • Everyday users who received a suspicious DM, friend request, recovery offer, or "support" reply and want a second opinion before responding.
  • • Creators and public figures targeted by impersonators — see the Creator Safety Toolkit and Protect Your Followers.
  • • Victims of fraud who need a free, step-by-step recovery plan via the panic guide and reporting tool.
  • • Journalists, researchers, and law enforcement who need a free, citable evidence base for impersonation and crypto-fraud patterns.

How GACS works

A user pastes a handle, wallet address, URL, phone number, or email. GACS runs a layered analysis pipeline across signals that include account-age math, follower-velocity anomalies, impersonation similarity against a database of known public figures, on-chain wallet history, domain WHOIS and SSL posture, blacklist matches, and learned fraud patterns from confirmed reports. The system returns a verdict (clear, caution, or scam), the specific evidence behind it, and — when confirmed — adds a permanent public page so the next person who Googles that handle finds the warning first. Full detail is on the How GACS Works page.

Why GACS exists

GACS was started by an independent engineer after a family member was scammed for $40,000 on X by an impersonator account that any honest 30-second check would have flagged. The platforms knew. The signals existed. Nobody made them available to the victim in time. GACS is the tool that should have existed that day — and the commitment is that the core scanner, the public scam database, and the reporting flow stay free forever for individuals, funded by optional creator-monitoring tiers and donations rather than ads, data sales, or platform partnerships.
