3. If the team offering the bounty hunters to pay a small amount for the bounty hunters to process the rewards then pretty sure they are scam. They just trying to scam even the bounty hunters.
I am not agreed with this point. A project which promises to paya little amount to the hunters can not prove the project is scam. Rather than promising of giving more reward which is unrealistic has a very chance to be scam after finishing their advertisements. Because when a project make a plan of scam they arrange their advertisement with a greedy offer for the hunters so that they get a huge traffic.
