+Griefing in multiplayer worlds without explicit permission is not permitted.

+### 2. **Private Lobby Rules**
+When in a private lobby, if you are found to be violating rules set by the lobby host and have made the rules clear to you, and despite that you continue to violate and be reported, action will be taken.
+
+### 3. **Exploits and Disruptions**
