Since there are many people join bounty and they dont understand the rules. They only want quick money by creating shity article and video. The most craziest thing is bounty manager accept those kind of article and video. Check the video they made most of it is reading webaite and whitepapper. I am not surprised if the client wont pay such video and article.
The rules bounty hunter usualy does :
1. Asking about bounty in the project main telegram.
2. Asking when distribution without reading announcemment.
3. Copy and paste article without understanding what the project is about.
By understanding the three points you mentioned, usually they are still doing scams and there is no guarantee that they will definitely pay because they can do whatever they want, the bounty campaign will look good when the developer has given the coin to the bounty campaign manager or escrow with the bounty manager so that the guarantee will paid.
