I'm basically use youtube toolbox a lot. I want 20 phone verified gmail accounts. Each need to have a channel. and all passwords, phone numbers, secret questions/answers neatly organized. I'm not 100% sure about some stuff on the subject so I would like to ask a few things such as: if youtube picks up high message volumes, do they ask for phone verification even after you have verified already? or can you verify some other way? Is gmail best to be used here? thanks please pm me.
