Its against the rules. rollback or no rollback and rules are there to be enforced.
Honestly, Ben, I don't understand why you are so damn keister kerfluffled over this. We were told the state of the server was temporary. We were told everything would be rolled back.
We were told we were allowed to "have fun" while the server is in its current state. (Yes, that means exactly what everyone assumed it did)
We've been green lit to have free reign over Smogcraft, and that's what we did. No permanent damage has been done and once the server is back and running with bukkit, life can resume as it always has. Calm thyself.
