It feels too early to have a reputation based system as there <5k active users on Farcaster and likely <1k on Lens etc.. Maybe i am missing something but dont see the need until these social networks become much much bigger last cycle there were a number of credit scoring companies that tried to a score based on onchain activity to enable among others uncollaterised lending but none worked out... no demand!
I agree that at this point it's not that useful when you are an active user of these platforms. But e.g., I'm not that active on Lens. So if I see a new Kiwi user, who has a Lens profile, I'd like to know more about them. For example, it'd be great to see their score to determine if they are an airdrop farmer/spammer, or a legit user. So when they post something in the comments that's not in line with our guidelines, I would know that e.g., they're a legit user and they might have just misunderstood the app's idea :)
