I Found Staff Abusing on My Skyblock Server

This is a super rich player on my Skyblock server and the player is a staff member so I had suspicion that he was abusing when I teleported to him it didn’t seem like he was doing anything suspicious I then decided to look around and notice that all of their chests were

Filled with diamonds he was super rich though when he wasn’t looking I replaced the diamond blocks with dirt and then I waited 10 minutes went by and he finally went back to his chest and after taking a look he was super confused that all the diamonds were dirt blocks but out of

Nowhere he started to act kind of sus he looked around before mining a moss carpet which led into a secret area and when I went down to Sea he was mining infinite diamonds I don’t know how this was possible but this was definitely not allowed so I came out of vanished to

Confront him and since he was cheating I turned his entire secret area into bedrock and then I took away his staff rank now for every time someone likes her comments he has to mind one piece of sand let’s make him mine one million sand
