Origionally, we had /spawn which took you back to the plaza and /unstick which jumpped you back to a valid location. Spawn was being abused, greatly, so it was removed. Double unstick was made to send you to the DR to replace spawn, in a way that wasn\'t at risk of as much cheating. /die was added later, and really replaces spawn in a better way. So yes, I think we could get rid of double unstick at this point.
Edited to add:
I\'ve accidentally died when trying to unstick before, so I know how annoying it can be. After next server update, the double /unstick will be disabled in favor of /die.
