It's very simple. Reseting the ladder is very much like reloading the matrix:
The One himself (G Fraizer) unpluggs from matrix (logs off the battle.net), goes back to the source (Blizzard HQ in Irvine), reinserst his code for a reload (logs in to his account on mainframe), reloads the matrix (resets the ladder). And voila - all anomalies (dupes, hacks) are gone and banished to Zion (non ladder). Well i hope it helps, if ou have any unaswered questions seek out the Oracle (blizz tech support). Good luck
