Im really not sure if Im supposed to post this in this section, but I had full diamond armor (chestplate enchanted) on survival, and one of the F3's scammed me, and shot me in the head when I asked them for a horse. Im not asking you to ban anyone, since Im not sure whether it was the hardcore one, or the semi-friendly one. Im just asking for my stuff back. Thankyou

Stealing is allowed, the only thing you can do is to ask them politely for your stuff back.
