Core Principle
No one is required to trust a website that abuses traditional CAPTCHA. You are allowed to walk away from any service that uses hostile, inaccessible, or suspicious CAPTCHA flows.
Your Safety Rules
1. Do not trust sites that use traditional CAPTCHA
Traditional CAPTCHA (especially reCAPTCHA v2 image grids and checkbox challenges) is widely abused, spoofed, and often inaccessible. If a site relies on traditional CAPTCHA for basic access:
- Rule: Prefer to avoid that site entirely whenever possible.
- Exception: Only proceed if you absolutely must (e.g., critical government access) and you feel safe.
2. Always hesitate when you see a CAPTCHA or “Verify you are human”
A CAPTCHA box or “Verify you are human” prompt should never be clicked on autopilot.
- Pause: Stop and look at the page carefully before clicking anything.
- Check: Confirm the site is one you intended to visit and that the design looks legitimate.
- Rule: Do not click the box unless you are absolutely sure it is trusted and not a traditional or fake CAPTCHA.
3. If you must use a legit reCAPTCHA v2, interact very carefully
If you encounter a legitimate reCAPTCHA v2 that you cannot avoid:
- Rule: Only click the image boxes and the verify button, slowly and deliberately.
- Do not: Trigger the “white-out” challenge or any unusual full-screen overlays.
- Do not: Click the refresh, info, or audio buttons — these are common points of abuse and can be blocked or hijacked.
4. If you see a fake CAPTCHA page, treat it as an emergency
Fake CAPTCHA pages often imitate reCAPTCHA v2 or other systems and may show strange error messages, broken pages, or web-only behavior.
- Immediate action: Force quit your browser.
- Next: Run a full malware scan (e.g., Malwarebytes Free or a trusted antivirus).
- If malware is found: Delete it, then restart your computer completely.
- Goal: Flush all active memory and start from a clean state before logging into anything again.
5. Prefer sites that use modern verification (e.g., Cloudflare Turnstile)
Some sites use Cloudflare Turnstile or similar systems instead of traditional CAPTCHA.
- Rule: These are generally safer, but you should still hesitate before clicking “Verify you are human.”
- Technique: When you click, hold your mouse button down for about 5 seconds to avoid rapid challenge loops or “Verification failed” messages.
6. reCAPTCHA v3 is safe and can be trusted
reCAPTCHA v3 is scoring-only. It does not show image grids, checkboxes, puzzles, or any interactive challenges. It silently evaluates risk in the background and assigns a score (0.0–1.0) to determine whether the user is human.
- Pure v3: In the Google reCAPTCHA Admin Console, developers can configure pure v3 with no v2 fallback.
- No v2 requirement: Forms using reCAPTCHA v3 do not require reCAPTCHA v2 at any stage.
- No fallback: v3 cannot fall back to v2 — the architecture does not allow it.
- Safe badge: The “Protected by reCAPTCHA” badge is legitimate, safe, and indicates a scoring-only integration.
- Rule: If you see the v3 badge, you can trust it.
General Anti-CAPTCHA Safety Tips
- Trust yourself: If a CAPTCHA feels wrong, confusing, or hostile, you can leave.
- Limit exposure: Avoid non-essential services that rely on traditional CAPTCHA for basic access.
- Use tools: Consider content blockers or browser settings that reduce exposure to abusive CAPTCHA flows.
- Separate devices: If you suspect malware, use a different device to change important passwords.
Why This Advisory Exists
Traditional CAPTCHA has been overused, misused, and abused. It can:
- Block access: Especially for disabled users or people in urgent situations.
- Be spoofed: Fake CAPTCHA pages can deliver malware or steal credentials.
- Cause harm: In some contexts, access failures can be life‑impacting or legally significant.
This advisory exists to remind you: you never have to trust a site that abuses CAPTCHA.
