You have the right to complain or stop ar remove yourself as a bounty participants but you cAn’t force bounty managers and there teams to limit or put a higher amount for all bounty hunters because they mostly love a very crowded campaign to help them find investors.
The bounty managers have their own decision for this problem. The fact that if the managers will be putting the purpose of the bounty campaign as the main aim and that needs a lot of promoters.
That's a good suggestion but we know that the reality is too far from your suggestion to be considered by the managers.
