Since its easy to backdoor KYC, its not that effective, reward users based on their community activities, but how about some other users around the world who speaks different languages, have to include them too.

Actually, I think it’s better to ban witches than to guide them,  
Witches are not necessarily all harmful,  
Witches can actually contribute a lot to the liquidity of swap and nft  
If multiple rounds of airdrops are used to motivate witches to stay on the Stark network, they will continue to interact and provide liquidity on the network, which is actually a good thing for the ecosystem and users

as of now, complicate task can push Sybil back…see Linea 9 weeks activity.  
Anyway, to raise the cost per wallet from single user could easy set the gate to screen Sybil. Because it’s no effect on normal user.

Preserving user privacy and decentralization is crucial in Web3 concepts. While addressing Sybil attacks during airdrops, exploring alternative techniques and community involvement can be effective without compromising these principles.
