The recent changes encourage people to use custom trust list. Why should we ask people to remove someone from their trust list? Isn't it better to exclude those whom you don't trust with their feedback? Problem solved.
But the purpose of default trust system is to identify the scammers and untrustworthy people by the newbie,so if we have flaw in the system we are redirecting the newbie to trust the wrong person just because how the system works.
