people using nbt cheats.

I joined a public realm and found someone who was a member so he had no special permissions, he was using nbt loaders to summon command blocks and do stuff that should be impossible after the patch. My discord is "LegionZM" if you need to contact. I have 5 clips of it and some important information. if a dev reaches out to my discord that would be greatly appreciated.
