Kubex300
Kubex300 appeared on April 14th, 2022 and would conduct two massive Mainpage griefs in the months following their arrival.
The first of these griefs erased more of the Mainpage than any attack since the 2015 Wipe. The second grief, a similarly massive onslaught of black blocks, would be notorious for its month-long presence over Spam Central.
All of the text erased by Kubex were restored by FP. This does not, however, diminish Kubex300's status as the most notorious griefer to have appeared since the chaotic days of pre-Wipe YWOT, when the site had far less protection against scripts and spammers banded together into factions.
Initial Waves(April 14th-April 16th)[edit | edit source]

Kubex first began griefing spawn in response to another user, going by hazel#1111, who spammed a large area around spawn with the message:
hazel#1111 knows how to write python
In order to one-up Hazel, Kubex spammed an even larger area with:
[kubex300 knows how to write nodejs:)] [sorry for the spam ¯\_(ツ)_/¯]
The message was later changed to:
kubex300 knows how to write javascript
An invite link was included in this iteration of the spam, leading to a Discord server where Kubex would talk about the situation at Spawn and take requests.
This alone destroyed more text than any previous griefs in the current Mainpage, with Kubex supposedly using five separate servers to paste his messages. And the attack was conducted at such a range that remnants of it can be found even hundreds of coordinates away from Spawn. But the scale of this initial wave would be dwarfed by what soon followed.
On April 16th, 2022, Kubex spammed the center with ASCII Among Us characters following a request from a member of their server. This lasted for roughly an hour, after which a bot cleared away some of the spam and Spawn briefly returned to normal.

Kubex's Bible(April 17th-April 18th)[edit | edit source]
On April 17th, 2022, Kubex got to work pasting the entire Bible into YWOT. It began to the right of the Spawn Cox and stretched downwards for roughly 3000 coordinates, causing a great amount of damage due to its proximity relative to the South Road.

The Bee Movie script was also pasted due to another request from Kubex's server.
The above texts soon became the targets of griefers, who were enraged to find that Kubex had created a script to periodically repair them. In the end they could only spam messages containing rhetoric against Kubex.
On April 18th, Kubex got tired of the current status quo and started clearing away the area around Spawn. Prior to this they supposedly claimed that everything within 1000 coordinates of (0,0) was going to be wiped. This plan would not be fulfilled, though the damage that ensued would be massive nonetheless.
Kubex's server was also deleted on this date. The reason for which is unknown, but it's possible that Kubex wanted to grief spawn in privacy.

After Kubex's mass griefing of spawn has concluded, both the Bible and the Bee Movie script were completely erased, with all text covered by them being restored.
Mass Erasure(April 18th - April 22)[edit | edit source]

Fairly self explanatory.
Starting on April 18th, 2022, Kubex began erasing all text in a growing rectangle around (0,0).
This would be done in a strange method, in which an area would be erased in a pattern before being erased completely. The reason for this is unknown.
Over the next few days this rectangle of nothingness would grow rapidly, ending around X:(-)121 and Y:(-)242 at its peak.

Spawn, meanwhile, was trapped in a cycle where text and art could appear only for brief moments before being consumed by Kubex's script.
And though there was little that could be done to fight the erasure, FP assured that a backup of spawn does exist, and can be used if things got too out of hand.

Spawn Restoration[edit | edit source]
On April 22nd, 2022, the area affected by Kubex was restored by FP. This was done using a backup of Spawn archived in 2021, so some text could not be brought back.
Following this Kubex disappeared from YWOT, seemingly due to the knowledge that any attempt to grief Mainpage on a large scale would be futile. It's also likely due to the fact that they had to pay for server time in order to execute a mass grief...
...or so people thought.
Only a week would pass before Kubex returned to start an even greater incursion.
Return of Kubex[edit | edit source]
On June 18th, 2023, Kubex returned and bought back their Bible. They also hinted at bringing back The Void, though no attempt has been made so far.
As of 2025, Kubex is still semi-active and would respond whenever they are pinged in the YWOT or OWOT Discord servers.

Trivia[edit | edit source]
- Kubex has a history of frequently changing their Discord usernames
- When he first arrived in the YWOT server his username was simply "kubex"
- Some time after the conclusion of his incursions it would be changed to "rani"
- Following a few more undocumented changes, Kubex settled on "leszek" which is still his username as of 2025
- (These are all nicknames however and his true username has been "nacpanyleszek" for as early as I can remember)
