Presumably people become members of a community because they want to. Because they find the social interaction, and the shared goals and values, attractive. Otherwise, why bother?
And, as I said earlier, “leaders”, or “councils” within the game only have power because the community chooses to give it to them.
It works just the same as real life. If you build relationships, try to help people, try to be pleasant and understanding, and if you genuinely like other people, then most communities will respond in kind.
If, on the other hand, you are destructive, negative, insulting, and rude, you will find that the community rejects you. People won’t talk to you. And if you’re going to invite that reaction, then why join a community in the first place?
So yes, you’re right. Leaders and councils within the game have no real power. They can’t physically crush those they don’t like. But that’s not the point, is it?
