config setting

Set to true if you want to disable players to be able to put bounties on each other.

enable_player_bounties: true

does not do anything regardless of its true/false setting. players are still able to set bounties
also your wording in the comment doesn't make sense. setting it to false should be to disable it. why does it say set to true to disable it?

Only Players with permission mobhunting.bounty can add bounties to other players.

enable_player_bounties: true is used for enabling /mh bounty

enable_player_bounties: false is used to disabling /mh bounty
