FAQ

Why did it connect to my server?
The bot checks servers at random to detect whitelist status. Seeing a short connection is expected behavior.

Is this “hacking”?
No. It’s a normal connection attempt + disconnect. It does not exploit vulnerabilities or perform attacks.

Is it allowed under Mojang/Microsoft rules?
The maintainer is not 100% sure and server owners should apply their own policies. If you’re uncomfortable with automated connections, you can opt out via ticket.

How can I block it?
If you prefer, you can block specific usernames or IP ranges at your discretion. The recommended approach is using the opt-out ticket so the server is removed from the checker’s dataset and banning the bots from your server.
