In line with the title, implementing restricted group moderation tools for new groups would result in significant benefits.
For example, a group under 50 members can't use moderation tools at all. Between 50 and 100 members, a group could utilize kicking and warning functionalities. Once a group exceeds 100 members, access to all moderation tools would be granted.
Moreover, it's crucial to limit moderation tools access to known/trusted users exclusively.
These restrictions are proposed to prevent groups abusing moderation tools in public group instances, leading to a negative impact on the user experience. Creators, particularly those with popular worlds, suffer greatly from such misuse. In some cases, the popularity of a creator can significantly decline due to the negative behavior of certain groups.
In a previous feature request, I requested that the creator of a world can disable group instances to avoid any form of external group influence. It could also be a solution.
