Well that was p4r4...He was not power happy. He was asking you a question and pleading the 5th does not apply to this. He was asking you how you got the diamond armor and he said after you were banned that you only had a stone sword in your inventory so it was a bowl of cr**. Even if you bought armor, how did you get the money for diamond? He asked you and you plead the 5th. Have a good day sir.
