OP's suggestion of the BTF token still leaves loopholes if the token won't be listed on any exchange. My question is, "How do hunters then get paid?"
He proposed that the token be airdropped to each Bitcointalk user based on his activity. Bounty hunters would get paid in whatever coin/token the bounty campaign intends to pay in. I understood that the BTF token would be some kind of insurance and guarantee that the campaign is honest and wants to perform all its duties, which includes paying bounty participants.
Other than that, I don't see the essence and usefulness of the whole suggestion. That's my point.
Me neither. I don't think it would do anything in the fight against scams. The token doesn't have any real value and is given away for free. If the suggestion was approved and the idea implemented, why would I simple not pay those free tokens, and then still go and scam everyone if that's what I wanted to?
