There should be no public amount and no bolt11. There should be attestation from the receiver that someone zaps or scams. That way everyone gets their precious 'signal' and not the rest. Ever notice how a hot zapped post tops out? Because the amounts are visible.
The social implications are important. Notice that venmo started out advertising publicly who sent money to who, and nobody uses that feature anymore other than venmo itself to enforce it's centralized rules.
