Thanks for the reply. Not sure how to parse it. Are you a Supporter of the Aggression Principle (a SAP)?
Edit -- I guess you're saying how do we know pledgers aren't cheaters. This is a valid concern and trust does need to be earned. Steem with a different portal, and reputation scoring formula based on public commitments kept, balances perhaps held as a bond, others willing to vouch for you, etc. will help with this. Earlier posts in this series have addressed this.
