It's not a good idea to attach a permanent social stigma to a person. That is part of the reason negative reps were removed, I'd imagine.
inner child: I disagree. The purpose of the moderators is to moderate. They are not better than the other members, but have shown to be trustworthy and good at what they do. Likewise the Benefactors are not better than other members - but membership simply recognises their efforts towards helping people and/or making the forums a nicer place to be. It is helpful for people to know whether they can trust the advice they've been given (and I do not mean non-benefactors give bad advice), as the reputation system alone is not sufficient for this job.
I am an entirely free entity. I have new resources open to me, but I still follow my own agenda and my own code of ethics. Being a benefactor does not make me better than anybody else or change the way I will act to people - and there would be a problem if it did.
