Reminds me of a bounty I ran awhile back where the team was supposed to pay after the TGE but severed all connection with me a month before the TGE. Might be the same team running the same scam. All the bounty hunters were never made whole.
Honestly, if a team approaches you with this sort of proposal and says they'll pay after the TGE, ALL managers should refuse the job. ALL bounty hunters should not participate either. Make the team escrow a large amount of money if they want to run a bounty, then take the chance.
