Nice topic although few months ago.
Nowaday, honestly bounty activity give me small reward.
Cause the major factor is a lot of participant that joined that bounty.
We can't blame developer team and bounty manager cause if many partisipant it will make spread the project nicely.
But try to limit member of bounty campaign I think good work for bounty hunter and make better prosperity.
But in my heart deeply, I want agree if limit members. Cause why? I think bounty hunter like another profession. And it spend time, mind, etc. The developer or bounty should be honor that.
