Duplication glitch and we want anti cheat for bedrock realms

There's a duping glitch basically all you need to do is use a crafting table or the one in inventory then you need a stack and one block of what you want to dupe then put the stack in the crafting table or the one in inventory and fill your inventory up with random stuff so nothing can be picked up then force quit the game so alt f4 load up go to crafting table or inv then you should have 2 stacks of blocks
