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.
One would assume this should become common practice for bounty managers and campaign managers. Especially those who've been around here and doing it for while, and have a reputation to uphold. I can see some newbie BM getting caught up in a scam like this because he hasn't developed a name for himself yet and is eager to get work, but these situations would be a lot less common if more scrutiny was employed by the more experienced ones.
