SilkTouchBookExploit - dniym/IllegalStack GitHub Wiki
ON BY DEFAULT - MC 1.14
Prevents a 1.14 glitch that allows players to hold a Silk Touch book in hand, and break a block. This will cause the block to drop as if a silk touch TOOL was used on the block, meaning items like glass, ice etc can be quickly mined without having a properly enchanted tool.
To enable / disable this protection use the following command: /istack toggle SilkTouchBookExploit
This protection has no extra options.
