Warden doesn’t like being cheated on, so hacked clients may get you banned from the server.

Many hacked Minecraft clients have backdoors, and/or malware hidden inside. It’s scary how many people mine bitcoins without realizing it!

Warden constantly analyzes cheaters and gets better over time.

If you were not cheating and got this error – you can help us find false positives by filing a bug report so we can investigate what happened in greater detail.
Lying in a bug report will make you have a bad time. Warden has plenty of data to figure out what kind of Minecraft client the affected player(s) were using.

If you don’t cheat, you will never be permanently banned. It’s that simple.

If you’ve been permanently banned due to repeated cheating or other infractions, you can fill this ban appeal form.
