Chunkban

A chunkban, is an exploit where player(s) are kicked consistently from the server due to an error involving glitched chunks. This is commonly linked to collision corruptions or chunks containing excess data.

Methods
Note: All methods listed are patched on 2b2t as of 20th April 2020


 * Sign - This method consisted of filling a chunk with 2MB of sign text, this is by far the most efficient chunkban method, therefore patched on most servers
 * 7-Layer - Consisting of the illegal cyto player heads, these could be placed in large quantities in a chunk. Taking around 2,000 to ban a chunk
 * Banner - Using data rich banners, a chunk can be filled up and banned with around 20-30 Layers
 * Furnace - This brute force method somehow got under the threshold of actually fitting into a chunk, it requires 44,000 furnaces and cannot fit into (2b2t's) nether
 * E-chest - a slight improvement on furnaces, but a pain to build with. Ender Chests are only useful when duped on mass and are harder to grief.
 * Enchanting Table - Very rarely used due to the frame rate issues when building, does not offer much significance over furnaces and E-chests
 * Classified - Experimental method that works in nether, can be set up with 1 person in around an hour

History
Claims of chunkban usage go back far since it has been a bug since the beginning of the game, so feel free to add your experiences here.

Early 2019 - Sign chunkbans were used around nether 0 0, along with the slogan "spawn's closed". This was patched by Spigot shortly after.

Nov 2019 - The Book Club used banner and 7-layer chunkbans throughout nether spawn to wreak havoc on queue times and new players. Use was discontinued after Hausemaster patched illegals and NoServerNovember was over.

April 2020 - The Bakery used furnace and e-chest chunkbans at key locations in the overworld to reduce queue. These had almost the same level of effectiveness as the much more compact patched designs.
 * 7th - 12th, Chunkbanning the comet at Ziggy town with a furnace chunkban.
 * 17th - 20th, Chunkbanning 0, 0 (e-chest), causing an amount of spawnfags and yesterfags to get banned.

April 20th 2020 - Hausemaster patches chunkbans though a rework of chunk loading.

June 2020 - Redstoner, Steve3 and ManaFilms discover a bypass, it is in experimentation and could be deployed on highways to ban dozens of players
