Additional, on the "Staff Decisions" thing.Staff makes the decisions. There should be no prejudism. Staffs decisions are final.
When staff give a ruling and then staff ban despite having ruled something was admissable... which of those decisions is "final"?
In cases of doubt or of double-direction the benefit of dount shouold be given to the system user along with the corrected ruling _for future_ - otherwise it almost feels like entrapment.
