Farcaster airdrops can avoid being farmed by bots by integrating anti-sybil mechanisms and focusing on authentic engagement. One effective approach is to use reputation-based systems where users earn airdrops based on their real contributions, such as content creation, active participation in discussions, and community support. Instead of simply rewarding wallet activity, airdrops could be tied to verified actions, such as completing tasks within the community or being nominated by other users. Implementing Proof of Personhood (e.g., through technologies like Proof of Humanity) can prevent bots from participating, ensuring that airdrops go to real individuals. Additionally, dynamic airdrop criteria that adjust over time—based on ongoing activity or engagement—can further reduce the likelihood of bots taking advantage of the system.
