Apriori, a trading infrastructure startup, faces scrutiny after a recent airdrop of its APR tokens. DL News reports that approximately 80% of the airdropped tokens went to a single Sybil (multi-account) group. On-chain data reveals suspicious activity. Around 5800 wallets received identical amounts of BNB weeks before the airdrop. This BNB was necessary to claim the airdrop on the BNB Chain, days before Apriori's official announcement. This suggests a coordinated effort to exploit the airdrop, raising concerns about fairness and distribution. The incident highlights the challenge of preventing Sybil attacks in crypto airdrops and the need for robust anti-Sybil mechanisms. ```
