Why would the system prevent banned users from accessing the merits system while allowing them to access the trust settings? If banned users can provide or remove feedback, we're in big trouble. The system will be tampered with, just as naim027 did with Timelord2026.
I don't know because I am not banned. 
But my guess goes to
- User only can modify their trust list after a ban
- User can not write a new trust feedback or remove existing trust feedback after a ban
- naim027 can confirm it if he want
