The unknown demon

Note:This creepy pasta is fake, I just dreamed it up! And it might not be of as good quality as the first one  "Iceman". With that out of the way let's get to it! So I continued playing in my Minecraft world after a good nights rest. I logged on and saw another player going through my chests! I did not open the world for multi player,  so nobody could join! I don't remember his name so we will just call it "The stealing demon". I told him "HEY!" in chat he saw and ran away! I checked my chest and there was nothing in them! Even my two stacks of diamonds were gone! In chat he said "Hahahaha". I replied What do you want for my stuff back?! He said he wants one stack of name tags luckily i had that in my inventory! I gave them to him and he gave me a piece of sand and teleported away! My cheats were on so i tried kicking him from the game. It did not work, I left the game. it did not work! I tried fighting him. Then he used /kill on me. I turned world into server and tried to ban him. It did not work! Made a new world. He followed me in! Joined a server. Followed me and destroyed it! Played a completely different game. Somehow came in and destroyed it. Tried Clearing computer It did not work! There was a file in minecraft called "Read". I read it and it said "The only way of getting rid of me is deleting minecraft, this folder, and everything in it and never redownloading it". I did it and everything was back to normal though, I cant play minecraft again. That is the end of this creepy pasta. And if this is too short feel free to delete i don't care.
