(adsbygoogle = window.adsbygoogle || []).push({}); From 25th to 29th of November the duplication glitch itself was working perfectly fine, ever since the 31st of November to the 1st of December the glitch itself still works fine however it no longer sticks. I've tried with 3 different methods of the duplication glitch and they all work however it does not stick.

I just done it about 5 minutes ago to my friend... I can assure you that it definitely still works although it may take a little longer to get into a game before a black ops error kicks you off the game, but it still works so don't worry

The glitch has been confirmed by multiple people to be working, so I'm going to go ahead and close this =D
