1. Username, UUID, IP(s), and short ban reason for each offender.

To view the content, you need to Sign In or Register.

2. What did they do?
They crashed the server by repeatedly switching a specially-crafted item from their offhand to their mainhand, which overloaded the server. The exploit is pretty well-documented, especially since I was the one who originally discovered it in September 2022.

3. What bannable offense does this fall under according to the community guidelines?
#7 - Exploits

4. Add logs and/or screenshots of the occurrence here, and tag any witnessing staff. Evidence of previous offenses that are not the direct cause of this request can also be added here.
