The strange player

I will tell my story. this is the night, I played Minecraft, I'm going to the Multiplayers and i played a server called KABOOM.

I have spawned in a mode creative, but, 1 thing, I saw a player called with some numbers and the server crash.

I restart the server and a strange player with satanic username was chating with players. The server crash again, but the server was closed.

1 minute later, I restart the server again and saw the world destroyed. After, in the list players I saw a ghost players and a players was really strange,

but, I'm going to the desert and a lot of lava in the desert and I saw a portail TNT. I respawn in the mode survival and in the list players I'm only two with the strange player

That all

I restart the game and the player are here, a strange player with a satanic username
