Would a client-side rule/UI feature help here?
- allow only one npub per username
- show if a user is active on Damus
It wouldn’t solve the NIP-05 or pfp imitators, but the handle is visible on a note and if it’s the handle I *know* is yours, then between two Damus users there is verifiability without reviewing a profiler’s history.
Not sure whether the above is possible, or what drawbacks it might bring…
