I use only one of them: bountyhive. It's really easy to the website and it's great that you don't have to report anything. But the rewards sometimes may become little
Actually automatic is what we seek as bounty hunter to not report anything to the manager because its annoying.
I dont like the bounty with need to report because its wasting time for me. I prefer to search another bounty manager. And sometime there is very strict rule. Thats my problem so those platform is helping much.
