Welcome to griefer part II. As some of you know about mob army and if you haven't check it but take away the mobs and what do you get a ninja who waits for the wright time. If you think your being targeted hide your items little by little in different spots and if they are being taken set traps. Then have tnt underground and keep a leaver in your inventory at all times in case of emergency. But this is a bluff but in extreme cases use as a last resort use it and right after you die you need to double tap sprint to your point of death to retrieve your items but don't bother looking for the griefer's items because he/her most likely are hiding there items. So if you have a griefer problem tell me and I'll fix it or have away you can fix it. Until next time. Good luck!
