Trust lists have to be public so there is accountability within DefaultTrust. Outside of that its also important to know who may be a good addition into DefaultTrust. I'm not sure I understand your comments about bribing people so I won't comment on that.
good points. imho you are right... sounds like i should go code some tool to make that list browsable.
my point about bribing was only that i may contact and bribe a user if i want his account.
eg some time ago (dont know if i still am) i was on trustlist of ABitNut. someone who wants to scam him could try to bribe me to sell my account.
