The landscape of crypto airdrops has dramatically shifted from its early days of mutual benefit to a more contentious environment, as highlighted by 12 landmark 'anti-farming' projects. These projects, including Hop Protocol, Blast, and LayerZero, have introduced mechanisms that challenge traditional airdrop practices, often leading to community disillusionment and trust erosion. Hop Protocol pioneered a 'community举报Sybil' mechanism, encouraging users to report suspicious addresses for rewards, which has led to community infighting. Blast introduced a 'points system' requiring users to lock up assets, benefiting large holders while leaving ordinary users with minimal returns. LayerZero's stringent sybil detection process before its token launch resulted in many genuine users being excluded, further eroding trust. These projects, among others, have contributed to a shift in the airdrop narrative, where retail investors are increasingly wary of participating in new projects due to opaque rules and perceived exploitation. The once-promising airdrop model is now seen as a cautionary tale, urging the market to focus on projects with genuine product-market fit and sustainable value.
