Scam-detector FAQ
What is a scam detector?
A scam detector is a tool that checks whether a website, crypto wallet, phone number, or social profile is linked to fraudulent activity — pulling from confirmed scam databases, community reports, blocklists, and technical signals like domain age and SSL history. GACS scans all four surfaces from one page, free.
Is the GACS scam detector really free?
Yes. Unlimited checks with no signup, no ads, and no upsell wall. Activating your free Shield unlocks saved history, watchlist alerts, and certified reports — but the scan itself is free and ad-free.
How accurate is a scam scanner?
GACS returns high-confidence verdicts when an entity appears in a confirmed scam database or has strong signal overlap (fresh domain + missing legal pages + suspicious payment flow, for example). For fresh or borderline cases, the verdict is Caution with the evidence surfaced so you can decide. No detector is 100% — always cross-check large financial decisions.
Does the scam detector work for crypto?
Yes. The wallet scam scanner supports Ethereum, Bitcoin, Solana, Tron, BNB Chain, Polygon, and more — surfacing rug-pull ties, drainer contracts, mixer usage, and sanctioned-address matches.
What's the difference from ScamAdviser, urlscan, or URLVoid?
Those tools are strong on one surface each (website trust score, URL sandbox, URL blocklist aggregation). GACS covers websites plus wallets, phones, and social handles from one interface, is fully ad-free, and offers a free public API with no signup. See /vs/scamadviser, /vs/urlscan, and /vs/urlvoid for honest side-by-side comparisons.
Can I report a scam I've spotted?
Yes — 30-second anonymous reporting at /report. Reports feed the same database the scam detector queries, so every report protects the next person.
