Minecraft Bedrock Hackers grief your realms/worlds with 1 item (CBE)

Hackers use an exploit (they call CBE) to grief innocent realms. They use items such as beehives, fish buckets, movingBlock and more. These can hold NBT data, which either spawns command-block-minecarts or npc, which can have actions such as turning everyone into creative mode, summoning tat, etc.

An example of this was the official voting server getting hacked, making it unplayable

 

This is a serious security fault, and needs to be fixed.
