ya you are absolutely correct as because more and more people are joining the bounty there should be some regulations.
I do not think it is necessary. There are many unemployed and they need a job that can help them to survive. You should not be so selfish. The more people involved, the more the project will be advertised
I think that there should be some restrictions on the number of participants and certain bodies. Since there are a lot of newcomers to the forum today, it is their number that must be limited, so do some managers.
