Okay, before people start playing the blame game, you both need to provide more evidence than just accusations.
@fireknight275, if you thought he was hacking then you can't just attack him and his base on he assumption.
@gyruss522, if he griefed your base then you need to provide screenshots and evidence that clearly show it was him. Because the whole issue is being brought to my attention through accusations, I cannot do anything to assist.
Before you both begin to start a flame war about who is at fault, you need to remember that both of you appear to be acting on basic assumptions.
Unless you or different staff member can verify what happened, all I can say is that I can't verify any of the accusations you have.
Seeing as this may be just a big misunderstanding, try to make up with each other and repair the damages together. After all, no one wins when someone gets banned for a simple mistake caused by a misunderstanding.
Mentioning the admin @Purplegirl and the server owner @MACMAN to see if they can potentially solve this while I'm away from my computer.
