Guest 2147483648

Context
For a bit of a backstory, it's been confirmed that the client for Roblox runs on 32-bit. This remained true until the end of 2020, when it was growing close to 2,147,483,647 signed in users on the website. Before the removal of Guests, it's been confirmed that just like regular Roblox users, it followed the 32-bit system: The minimum limit is -2147483648, and the maximum limit is 2147483647. Whether you're familiar with this or not, Guests have negative IDs, so that means you would've been able to play as Guest "-1" or Guest "-2147483648", right? Strangely enough, if you were to attempt this before the removal of Guests, and enter the GuestID "-2147483648" it wouldn't work. Unless if this implied this value was exchanged for an ID 0 user, (which was rumored to be Admin...) what would've been so awful, that joining as this Guest would be impossible?

The Origin Story
Roblox Guest Users, unlike Signed In Users, were not in danger of getting banned. They were public accounts with no inventory items with the exception of their assigned outfits. No direct consequences would be made due to this. People took advantage of this under looked flaw, and started to become rogue as Guest Users. Exploiting and causing explicit and disruptive behavior to what their imagination desires. Popular placeholders being Guest 666 or 1337. Some even playing as Guest 999 or 9999 which was falsely labeled the "final" Guest. One that didn't get much attention was Guest 3648. (Short for Guest 2147483648.) To the average user, this is just a randomly generated number. To those who are knowledgeable of it's meaning, they will know it's the number of the true final Guest on Roblox.

The Final Straw
Anonymously, someone kept joining as Guest 3648, causing game breaking glitches. This user went on popular games that doesn't have an anti-hack backup script, and would play audio IDs on unholy screams and inaudible weeping. As if whoever was recorded was in pain. This caused trauma to new and youthful users, discouraging them from joining any public servers in fears this would happen again. This only got worse when aged scripts were breaking, making games with an old anti-hack backup ineffective from stopping these incidents. Even with exploiters seeking this opportunity, they were held back with the possibility of getting (IP) banned. Though this wasn't going to stop Guest 3648. And if something were to happen, he would make it worth the while. He joined a Stamper Build server, and he plastered every wall with bypassed gore decals, morphed avatars to be covered in blood, and changed the lighting and sky deep red. Messages kept popping up saying "ANYBODY CAN KILL... ANYONE WILL." Users soon found a Guest flying across the map, unbothered by the incident. Connecting the dots, people started saying "It is the Guest!" and "Report him!" This didn't last long, as he begin the disable chat. Though the word's already been spread across the server, and eventually got out on Forums. This lead to a massive spike of reports to the Guest user. This caused an investigation, which took time due to those unable to address which Guest it was. And as mentioned before, banning is not normally a protocol for Guest Users breaking the rules. An admin, determined to uncover who's responsible, quickly joined Stamper Build to investigate the scene. Server hopping to where every Guest was on, until he found something unique. Then he found it. Almost nothing to say to describe how sorry he felt for those effected, and how many times or how long this has been happening. He looked around for Guest 3648. Unknowingly, he was flying above him witnessing the whole reaction. He sent another server message, saying "HELL AND HEAVEN SWAPPED PLACES, AND I AM THE NEW GOD IN THE SKY." He was shook by the implication that he has been there the whole time. He looked up, and there he was. They said nothing for a while. Then the admin said "I'm warning you to stop. If you don't, I'll ban you." Waiting for a response, he soon exchanged this "YOU CAN NOT DETHRONE A USER ANYONE CAN BE." Knowing that he was implying the account wasn't private to him specifically, he would risk deleting a public account. Despite this, he replied "You ruined it for everyone. I hope it was worth the troubles." The admin left the server, and looked at the IP address for cookies. This would soon lead to him finding what Guest he was playing as, and terminating both his main account, and his prized Guest account. The final Guest, Guest 2147483648, was soon defeated. This scared off most users from attempting exploiting on Guest accounts again, but some continued to repeat the same mistakes. Five years later, it's been announced that Guests would be removed. It hasn't been said direct that this would be to prevent hacking on a public/guest account, but people knew what this would mean. The final Guest was unknowingly the root cause to why Guests would be put to rest. Ironically, starting off from removing Guest 2147483648, to removing 2,147,483,648 Guests.

Conclusion
Now, Roblox runs on 64-bit. We can now have up to 9,223,372,036,854,775,807 accounts. 9 quintillion users! We won't have to worry about running out of IDs for users ever again. If Guests weren't lead to their widespread fate... The new throne to being the final Guest would belong to Guest 5808. (Since the minimum limit for 64-bit integers is -9223372036854775808) If Guests were brought back now, would the final Guest make it's second wave under a new assigned number? Let's pray that it would never come to this.
