Vault 8166 public server incident

This happened somewhere last year. When I got home from school I got to my computer and started playing Roblox. While playing, my friend told me that he heard of someplace called "Vault 8166". I later found out that there is a supposed "guardian". I got interested in the game so I went to check it out. I have videos but I can't upload them since the site does not let me. The videos would contain me finding the guardian running around in the area with the truss leading to a room *I don't know what It's called*. Me getting caught by the guardian in the spawn area. And two people talking to each other. Most likely hackers. Here is the conversation:

Unidentified user 1: Do you know what happened to the panels?

Unidentified user 2: They said it was shut down due to this place becoming public.

Unidentified user 1: Oh, that's right. Do you have the private server?

Unidentified user 2: Yes, join me.

Unidentified user 1: Sure.

* Both the users left the second I would go to investigate.*

But that is just the beginning. I walked around the place for a while before I stumbled upon someone. He was walking around the truss area where I saw the guardian. I said "Hi" and here is how the conversation went:

Me: Hi.

Other user: Hello.

Me: Did you see the guardian?

Other user: Yes. he almost caught me. They said my information would be leaked if I got caught by the guardian.

Me: Really?

Other user: Yes, wanna follow me up there so no one will be listening.

Me: Sure.

* We got up to the top of the vault. There were monitors and some weird props. Probably deadly hacks*

We discussed the vault for about 5 minutes when a user came up to us. He was the "Other user"'s friend.

Other user: Hey

Other user's friend: Hi

Other user: We were discussing the vault. Wanna talk?

Other user's friend: Ok.

* Not before we could even say the next word. Someone came up to us. He was all talking in glitch text.*

User talking in glitch text: Ḧ̸̡̼̮̼͇̞͙͉́̂̉̒͑͆̄̿͠ͅḯ̴̪̠̜̗͖

Us: Hello?

User talking in glitch text: Ḭ̵͘ ̶̙͐k̶̪͘n̴͕̉o̶̰͊ẁ̴͜ ̸̔͜y̶̥̽ô̷͕u̸͕̍.̷̡̊ ̷̼͊D̵̥̆ò̴̩n̷͍̑t̸̲̆ ̵̩̓ḇ̸͋e̸̦̾ ̵̲̋a̵͈̓f̸͓̐r̸̩̿ą̷̕i̵̺͌d̸̛͉.

Us: Huh?

User talking in glitch text: I̸͂ͅ ̵͍́k̵̠̃n̶͚̓ọ̴͌w̸̳̎ ̵̙̓ẘ̵̙ḥ̶͐y̷̞̾ ̵͖͑i̸͚͝ ̵̹̃ạ̷̄m̶̲͑ ̵̞͊a̴̦͂n̸̡̚d̶͇̕ ̶̨̄ý̴̩o̷̲͋u̶̺̔ ̶͓̅a̵͖͂r̴̥̒e̵̼̿ ̶͎̅h̵̫͐e̷̥̍r̴͇͝e̸̯͑.

* Then he ran onto the Other user's friend. He was kicked from the game. We also leave since we got scared.*

Me and the other user saw that the User talking in glitch text had a green dot next to his profile. Meaning we could join him. He was playing in an emptly baseplate. When we joined him. He was not very friendly:

User talking in glitch text: Y̷̤̊o̸͙̔u̶̠͌ ̵͓̎s̵͈̚h̸̘͒o̵̘͘u̵͚͋ḷ̸͐d̴̥̀ ̴͍̄n̵̘̚o̸̭̔ṭ̴̇ ̸̜͋h̷̫͌a̶̭̽v̸̩́e̶̺̒ ̷̱̀j̸̻́o̸̬̔i̷̜͑ǹ̶͇

Me and the other user: Huh?

* We were kicked from the game with the error code of 8166*

User talking in glitch text's description was changed to "I will kill other user's family"

Other user then unfriended me. His description was changed to "You're next". Then he went offline forever.

This is also the story of why i dont play Vault 8166 anymore. Thank you for listening.
