Frequently asked questions

GACS (Global Anti-Crime & Safety) is a free public-safety tool that detects social-media impersonators, crypto scams, phishing links, and fraudulent websites. Paste a profile URL, domain, or wallet address — get a Safe / Caution / Danger verdict in under 5 seconds.

Yes. The core scanner — social impersonator checks, website checks, wallet checks, and the public scam database — is free forever for individuals. We never paywall safety. Optional paid tiers exist for creators who want continuous monitoring of their own following list.

GACS was built by an independent developer who watched a family member lose $40,000 to a fake crypto influencer on X. The site exists to make 30-second impersonator detection available to anyone before they send money, click a link, or DM a fake support account.

No. GACS is an independent public-safety project. We are not affiliated with, endorsed by, or paid by any platform, exchange, or government.

Each scan runs the account through 30+ signals: account age vs claimed history, handle similarity to verified owners, follower / engagement ratios, bio keywords associated with scams, the verified-handle registry, learned patterns from confirmed fraud reports, and live image hashing against known scam profile pictures.

On benchmark sets of confirmed impersonator accounts, the scanner currently flags 94% with a Caution or Danger verdict and produces a false-positive rate under 3% on verified owner accounts. Accuracy improves daily as confirmed reports feed the learning loop.

Verdicts are point-in-time. Scammers swap profile pictures, change handles, and add or drop blue checks within hours. We re-evaluate from scratch on every scan and incorporate the latest learned patterns.

X (Twitter), TikTok, Instagram, YouTube, Telegram, Discord, and arbitrary websites and wallet addresses. Facebook and LinkedIn are on the roadmap.
