The best free Discord verification bot (captcha + VPN checks)

What a verification bot should do

• A real human check. A captcha that bots cannot click through, not just a reaction on a message.
• Hide the server until they pass. Held members should see nothing but the verify channel, even channels that are open to everyone.
• Catch the tricks. VPNs, proxies, Tor and brand-new throwaway accounts are how raids get in. A good bot checks for them.
• Low friction for real people. One quick check, no waiting on a moderator, no commands.
• Actually free. The captcha and the anti-alt checks should not cost extra.

Why mimBo’s

• Cloudflare captcha. Every new member passes a real human check before they get in.
• Quarantine and lockdown. A quarantine role plus automatic channel lockdown hides every channel until a member verifies, so raiders and bots never see the server.
• Free VPN, proxy and Tor detection. Tor is turned away, VPNs are allowed only on aged accounts (with a heads-up), and new accounts on a VPN are stopped. No paid API.
• New-account checks. Set a minimum account age, and hold brand-new accounts a little longer with strict mode.
• Verify once, everywhere. Pass once and you are trusted across every mimBo’s server, so real members are never re-checked.
• Configured on the web. Set it all from a dashboard, with a customizable verify message rendered on the same card styles as the rest of the suite.
