Maybe they should have to rise to the rank of Treasurer before being able to rate, then the other members can get to know them.
If they don't post, we don't see them and they can't be banned by the presidents and we don't know who is doing it so we can't tell Agoracom who is doing it.
that's it in a nutshell! that was the single best suggestion i've ever seen on agoracom. people should actually have to contribute something to the agoracom community before they can rate their peers. that would eliminate the problem of lurker/bashers lowering the ratings of hub leaders and other investors alike.
i don't think it's asking too much of people to reach the rank of treasurer. if they're not willing to share information, they can still read the board and recommend posts, but why should they have any say in what the ratings are?
