The problem is I don't have a duplicate Adsense! So, yes I will join a network If Adsense keeps telling me that I have two Adsense account, because I only have one Adsense account I don't know what they are talking about, they send me email saying that this address is a duplicate account but it's the same address I use to sign in to my only one original Adsense account, and I was using it for two years now so, maybe their system is going crazy!
So if that problem won't solve then I will have to join a network, I don't have a choice.
About youtube monetization What I mean is that if youtube reviewed your application before Adsense was disabled and let's say that youtube accepted you in the program 'monetization enabled' and after that your Adsense go in a review state and got disabled so the monetization will indeed be disabled on youtube but, if your Adsense get activated then youtube monetization will automatically be enabled again because its already in the YPP, youtube is already accepted you in the program and the issue is with AdSense now,
So, What do you think Mr, green eyes!
