Scary user Acosmistt

So one day, I was on Roblox and I felt pretty bored bc my life is a mess and I have no soul, so. I was looking for tycoon games, and then I was looking for scary games. I was playing this game called "Chucks Residence", and I saw an avatar/user sitting in a chair in the shade inside the house. He was just sitting there, and in my opinion, it was creepy. I stopped in front of him and said "Hey." After I said that the user jumped up and did a wave gesture (/e wave), and left the game. This user has no clothes, and he has one game that I am scared to even play. Why? Well, I am a very curious being and I decided to check this dude out on his profile. He has some quote about a forest or something, and he has a game called "Nothing." Whenever I visited my profile, my computer shut off. I was very confused because the computer I have was on the charger and is also new, which doesn't make any logical sense of why it would shut off. When I tried to access Roblox again, my password wouldn't work. I still dont know what his game has, and I do not care of what it has. But yea, that was my experience.
