Agree wholeheartedly. Scott Jenson (npub1m8t…zu6r) had some great initial ideas on this. Here's some of the controls he suggested as a starting point:
- limit the total # of endorsements one person could make
- rate limit the speed that actors could make endorsements
Enforcement is up to the listener. Looking at who and how you've endorsed, do I believe you? With this, a botnet with 1000 self-endorsing sock-puppets could be identified automatically and silenced.
