Tonight I posted my server on PMC within 30 minutes I had already had 3 hackers on the server. They destroyed my spawn. I'm currently rebuilding the spawn. I have world guard region protection around the spawn. Also when players join, they are automatically set to guest. Guests have no build permissions and no commands of any kind. To get out of the Guest group, you have to pay $3 per month. How do hackers get access to commands like that ? How can I avoid this from happening again?
