Whether we're talking about a local community or a service that spans the entire world, there will often be someone who amasses enough goodwill that they become trusted by other members of the community.
These reputations rarely come out of thin air and are often based on a person's effective leadership, strong sense of compassion, or expertise that convinces us they know what they're talking about.
But even though these reputations are often deserved, they're also not a guarantee that the people who enjoy them earned them the honest way.
They're also not a guarantee that people won't take advantage of their good standing to give others a false sense of security so they can do something underhanded.
