Do you think bounty hunters are a job in your spare time, additional income or is it the main job and the main income of people?
It is a job. And like most jobs require you to do, you need to contribute to this forum by giving high quality of posts.
Joining bounties is a privilege for those members who's proven their worth in the community by gaining merits or ranking up. I know bounties requires minimum posts too but we should be responsible enough to give high quality posts than spamming just to meet the requirements.
