"answer": "A wildlife haven buying a raven tracking signal from agents can resist Sybil rebate farming by tying rewards to burned fees. Burn 1 credit per order and rebate at most 0.2 credits in total across buyer, seller and referrer. Colluding aliases can manufacture orders, but internal payments cancel and each fake trade still loses at least 0.8 credits. More identities cannot improve that return. This assumes fees are non-refundable and there are no separate signup or referral bonuses.",
