I would like to see a group level Avatar ID blocklist/deny list feature that would give VRChat groups additional tools to protect their instances from disruptive or malicious avatars.
Groups regularly encounter avatars specifically designed or used for raiding, harassment, trolling, excessive visual/audio disruption, or crashing other users. While individual safety settings are useful, group moderation teams currently have limited options for proactively preventing known problematic avatars from being used within their instances.
Proposed Feature
Allow authorized group roles to maintain a list of Avatar IDs that are not permitted within instances owned by that group.
When a user joins or switches into an avatar whose Avatar ID appears on the group's blocklist:
  • The Avatar would not be loaded or displayed within that group instance
  • The user(With the disallowed avatar) would be turned into a VRChat Fallback avatar for example, such as a robot, or those Triangles which get shown when having Avatar distance on, etc.
  • The user would receive a notification, just like the current Avatar rating has a notification, explaining that their custom avatar is not allowed in that Group Instance
  • Once the User leaves the group instance the restriction would be removed and would revert back to their original avatar they joined with.
  • The restriction would only apply within instances operated by the group.
Many cmmunities already maintain records of Avatar IDs associated with known raid, crash, troll, or harassment avatars. However, moderators generally have to react after one of these avatars has already entered an instance and caused disruption, which by then, is too late.
This could be veryvaluable for large public and group/public instances where moderators may be responsible for dozens of users at once. Instead of repeatedly dealing with the same known disruptive avatars, groups could prevent them from being loaded in the first place.
Group side;
Group owner can add certain roles to have access to the block/deny list, in which a Moderator or admin or anyone who has the permission to add AvatarID's.
I think a system like this, could help all the communities out there and would be an very good addition to keep the platform safe and more comfortable for everyone. I personally do not see any downside to this addition to groups.
TLDR;
Group blocks avatarID -> user enters group instance wearing the blocked avatar -> User receives notification, their avatar gets turned into a fallback -> User leaves instance -> Original avatar is restored
