If everyone agreed not to work unless they got paid a certain amount you wouldn't be used and abused. Why not try to form some type of an online union so you guys are treated fairly and with respect.
Bounty project can amend rules as they see fit during course of bounty, but once the changes made are too extreme or are seen as a way to deprive bounty hunters from getting paid, then I agree that certain measures should be taken which includes red tagging and flag creation.
