This is just to warn people in creative about griefers, please do not add people you dont know to your plot! Even if there is a rule "No griefing" that doesn't mean there wont be any griefers joining and asking for add/trust to your plot, if you really have to add someone you dont know to your plot, just do /p add dont do /p trust. I got an perfect example what you should not do! DO NOT ADD PEOPLE YOU DONT KNOW!
