OzFormers, the entity, owned by Griffin, did not create and does not manage that group. However, any issues with it would come back to Griffin, which hardly seems appropriate when Griffin isn't even a Facebook user. Moderating, removing, assessing misbehaving all seems completely unnecessary and problematic, when the considerably simpler alternative is renaming it.
What's wrong with a group chat under a different name?
I've said all I'm going to say on the topic. It's not my brand or entity, so it's not really my problem and in the end, it won't affect me. I'm also no longer an admin in that group, so I can't affect change anyway.
