Hello all, I can not log in "DoubleClick Ad Exchange" because of my AdSense account disable for invalid activity. Please tell me how can i log in my "DoubleClick Ad Exchange". Please help me. Thanking you.
What's the message that it gives you? Sounds like you need to take a look around the Google DFP Support area.
Well in that case contact Google Adsense support team with proper proofs of the invalid activity and get Adsense account un-banned to log in to Google DFP account.
I guess because I've not been to this site in a while that it's not letting me add in a link, so just do a good search for the Google DFP Support area and you should be able to find it pretty quickly. Being logged in will help you get to the right page instantly.
Your Adsense has been disabled for invalid activity this means your account has been suspended / banned and unless you can prove your traffic / clicks were not invalid you will not get your account back.
