Nuking
From Kaboom Wiki
Nuking is when players of Kaboom servers make the server unplayable for others. They may do this with several methods, such as crashing the server using exploits, deopping everyone and setting everyone's gamemode to survival, or spamming the chat. They often used command loops to repeatedly run specific commands.
Previously, nuking incidents were very common, but within the past few months, they have occurred less often.
