Chunkban

'''A Chunkban is an exploit where player(s) are repeatedly kicked from the server due to an error with chunks. This is commenly linked to oversized chunks'''.

Methods
 All of these 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

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

Early 2019 - Sign chunkbans were used around nether 0 0, along with the slogan 'spawns 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 hause patched illegals and NoServerNovember was over

April 2020 - The Bakery used Furnace and E-chest chunkbans at key locations in the overworld to again, reduce queue. this accomplished nearly the same feat as the much more compact patched designs.

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