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?
now you have to be more selective in choosing which bounty you will follow, lower your expectations and follow all of them (bounties that pay tokens) if you can because maybe one of them will pay you. but if you want to get a bounty with a definite payment then look for a bounty in the "service" section (which pays bitcoin) because it is more certain to get paid every week.
