First of all thank you for at least sharing this news that this is a scam bounty. Because at the end of a bounty, the participant has to repeatedly go to the telegram to check when the payment will come.  Participants at least don't have to do this anymore. Because the bounty manager or the team never says that the project is a scam. If you have any proof that the bounty is a scam, you can report it to the Scam accusations board.

But one thing I do not understand is why you are congratulating the participants for not getting the payment? What is there to celebrate?
