Currently if you are the creator of a world, you have moderation powers in all instances of that world. Most notably, you can kick people without a vote-to-kick. This is an old rule from before Groups were implemented in VRChat, and I believe it has become redundant now. Current world creator moderation powers:
  • Has moderation powers in any instance of the world (even in private and group public instances)
  • Can warn users
  • Can force mic off
  • Can kick users
  • Can see people that blocked them on Here list
  • Can see who started vote-kicks
If you incur the anger of a world's creator, they currently have the ability to simply kick you on sight from any instance of their world. And if the world creator is controlling enough, they can patrol all public instances and completely prevent you from using public instances of their world. If you happen to share the same friend groups, they can even join friends+ instances and kick you there too.
With the new Creator Guidelines, world creators are not allowed to automate blacklisting of people from their worlds using Udon scripts, and in-world moderators aren't allowed to punish people using udon moderation tools unless the they has broken rules in that instance. However there are no rules saying that a world creator can't just instant-kick those people on sight using the world creator moderation powers.
I believe moderation powers should be exclusive to group moderators in their instances, and instance owners in their private instances. The world creator should not have moderation powers in public instances, in other group's group public instances, or in other people's private instances. Basically, just remove the world creator moderation powers.
There are feature requests for the exact opposite point if view too. Some world creators want more control. But those feature requests has been said to be redundant now that group public instances exist.
