We do have a members and staff page somewhere just hidden atm whilst atoru works on the site more.
As for the ban list we have http://shapethecube.net/forum/m/41326053/viewforum/7756458
this has all those that have been warned or banned and any reports made by players.
I will ask atoru regarding the staff and member list if he has plans for that.
Thanks for the suggestion hope this helped
