Bookbanning

Bookbanning is the practice of giving a player several shulkers full of books with maxed-out characters in each book.

Ban books are books with obscene amounts of characters inside of them, and they should not be confused with dupebooks. It is often made so that it will overflow the packet's data, and if the packets are too large, you will be book banned. You will constantly be bookbanned since when you log on to the server, you will update your inventory, and being kicked again. Ban books are often renamed to other items to trick players.Bookbanning was first discovered by Jumbo_Warrior, first used on thesheergenius, then popularized by _Prismary.

Hausemaster stated in early June 2019 that bookbanning would be fixed and that anyone who is book banned can log in again.

Bookbanning was used by The Book Club to book ban over 400 newfags during October 2019 using "chambers" which had the same design as trapped nether portals, except they had dispensers that dispensed book ban shulkers to the new players, instantly updating their inventory to ban them.

Bookbanning was just recently patched by Hausemaster but it took away the functionality of .peek and Preview, popular hacks that allowed you to see the contents of a shulker box without opening it.
