We have full GM abilities.
We take immediate actions under some circumstances - for certain issues we must get a hold of a CS employee to be of assistance. This could be a missing Armas purchase or accidental deletion of an item, etc..
I think you misinterpreted what I meant by "almost exactly as another player" I was simply implying that we still just have two eyes to watch over a pretty large map. Expecting us to immediately spot griefing taking place while we are 500 meters away looking at something else is a bit out there. We do our best, but we are much more effective when people communicate with us
Banning is a touchy subject. As Matt has stated in the past this is the last action we want to take as it rarely leads to anything positive. Cases where banning is considered are carefully inspected before an action is taken. Banning on sight or on the spot is rarely possible, or wise.
