According to market news, X may hide all users' "likes" by default. In this regard, X engineer Haofei said: "Yes, we are making "likes" private. Public likes will incentivize wrong behaviors. For example, many people are afraid to like content that may be considered "excessive" because they are worried about retaliation from malicious people or to protect their public image. Soon, you will be able to like without worrying about who will see it. Also remind you that the more posts you like, the better your "recommended for you" algorithm will become." Vitalik Buterin commented on Warpcast: "This is a good decision. Preference fraud is a big problem in society, and we need to see people's true opinions. It would be very cool if Farcaster could follow suit and adopt the method of implementing zero-knowledge likes (ZK likes). Maybe Zupoll's technology can be borrowed."
