As to the question here,
If you want to leave you need to request unlink via youtube.com/features/ page. Having your channel linked to freedom dashboard changes nothing, simply leaves you with the access to it to check the previous payments and such, other than that you will still be able to partner with other networks (After you are fully unlinked from us via youtube, which takes 30 days from the time it was requested)
Lastly "how do i delete my dropbacktv account" Could you elaborate on this ? I do not know what dropbacktv is to begin with.
