Recently, while working on L2 tasks, I took a quick look at on-chain privacy issues. To put it simply, ordinary users shouldn't expect "complete anonymity"; it's more about "not being easily linked." Wallet addresses are publicly displayed there, and there are too many people who can look them up. The compliance line is becoming clearer: you can be low-profile, but don't expect to dodge all audits or tracking.

I'm not regretting the outcome, but rather regretting that in the past I took shortcuts by authorizing my frequently used addresses everywhere and even liked to share records in groups... Now I can only clean up authorizations while splitting addresses by purpose; if I profit, I withdraw, and there's no attachment.
By the way, I saw a heated debate over NFT royalties. Creators want income, while the secondary market wants liquidity. Ultimately, it's also about "rules written on the chain ≠ guaranteed to be enforced."
Lower your expectations; the only thing you can control is your own risk exposure.
