that's the problem. because sometimes most bounty hunters just become fanatical followers of the bounty manager. and when he published a bounty hunter campaign his followers would always participate regardless of the project's capabilities.
even though some bounty managers have clearly stated that they only post for the bounty thread and are not part of the manager and team. remember we should read more.
You can't blame bounty hunters, one of the criteria of bounty hunters when joining a bounty campaign, is the bounty manager's reputation because they know that bounty managers have their own criteria on what to look for a project, but even bounty hunters make a mistake I have seen a lot of bounty managers, losing their reputation because of the projects they are involved with, so do your own research too.
