 World-Specific Rules
 
 Griefing is anything that is destructive to the work another player has done, whether taking materials or placing them. Creating a player death trap is also considered griefing.
 
 In PVP-allowed situations, you may keep items dropped by a player you killed.

 Stealing and taking from chests that are not yours is not allowed
 
 PVP is optional

 Forum Rules
 
 Familiarize yourself with the search function
 
 Use the most appropriate board for your post topic
 
 Use proper language
 
 If you ever need to submit a ban appeal, make sure to do it in the Ban Appeals forum using the appropriate format.
 
 Do not post on other people's ban appeals unless requested to by staff.
 
 Voice Chat Rules
 
 Try to be in the correct channel for what you want to converse about
 
 Do not be a nuisance to other users
 
 Do not come on just to demand staff do things for you
 
 Refrain from explicit language
 
 It cannot be emphasized enough that if it's your name connected to a rule-break, it doesn't matter who really was playing on your account, you are responsible! The best defense against getting banned is following the rules and not allowing others to access your account.
 
 
 
 I double checked your application (That I accepted in may, I believe.) and you said 'yes' when asked if you read and understood the rules.
 
 So, if you wish to continue to try to clear your name, I am all ears.
