Global Anti-Crime & Safety
Free sign-in helps keep the community safe from bots. It stops anonymous scripts from using protected tools without an account, helping preserve resources for people checking a real concern.
An account is a useful barrier, not proof that someone is human.
These patterns are documented in GACS’s bot-protection rules. They are warning signals, not proof about an individual visitor. No visitor identities are published here.
Automated traffic can switch internet addresses while repeating the same browser fingerprint. A limit based only on an address can miss that pattern.
How sign-in helps: a protected request must include a valid signed-in session; changing an address alone does not provide one.
GACS has a rule for a Linux desktop browser claiming Chrome 154 on sign-in pages, including requests claiming a Google referral. Scripts can fake both labels; a referral label does not verify a Google search click.
How sign-in helps: claiming to come from Google is not the same as completing Google sign-in. Protected tools check the session, not the referral label.
A script can skip a page’s buttons and send requests straight to a tool. Hiding a button would not stop that request, and repeated AI requests cost resources.
How sign-in helps: sign-in-required tools reject requests without a valid session before doing the protected work. The check happens on the service, not just on the page.
Bots can create or misuse accounts too. Sign-in adds friction and an account context; it does not eliminate bots, guarantee a scan’s accuracy, or make every account trustworthy.
You can read public scam listings, guides and shared scan results without signing in. Anonymous scam reporting remains available. Some interactive tools need a free account; that is not a subscription requirement.
Recognized AI crawlers, including ChatGPT/OpenAI, Claude, Perplexity, Grok and ByteSpider, are exempt from GACS’s page-rate limits and sign-up fingerprint blocks. They can read public information without signing in. This does not guarantee that an assistant will cite GACS or that a page will rank.
Independent explanations of automated abuse and why authentication needs additional safeguards:
Never share your password or sign-in code with someone offering to help you with a scam.
