After running several bounty campaigns I have noticed that they only attrach bot accounts, multiple fake accounts controlled by one person or low quality accounts that can not even give adequate comments - it is not the same as it used to be back in the days in 2018. Where has all the quality crowd gone?
I think for now there is no quality bounty (project) so many people leave this forum. but when there is a good project then I am sure they will return to take part of the bounty provided by returning to being a project participant.
