So basically you want to force everyone to customize their trust list instead of using the default list?
That is something already being considered by theymos:
I don't think doing such a thing will stop the trust farming by DT1 members. As long as you can gain positive trust by adding someone to your trust network, it will be abused.
True, but if there'd be a (guided) process for generating your own trust list, the additional benefit would be that a lot more people would actually understand it. Because as I see it, the majority of BCT users doesn't even know how it works, only that red/negative trust is bad but they have no clue how it comes to red trust unless they are affected by it in any way. Imo a system - no matter what system - only works if the majority understands and uses it (correctly).
