I have watched a number of decodes presenting SB2 work. None of them were actually SB2. They were people presenting his work. Weeping Angel, War Drummer, As we Know are some of the ones that I have seen.
I’d like to see something presented by SB2, if you have a link, would you PM it to me? Thanks.
They are posted on his site and then he posts as SerialBrain2 on https://voat.co/v/greatawakening/ or https://voat.co/v/theawakening/
He doesn't do YouTube but has given permission to the Tubers you mentioned to read his Reddit posts. They have to read them word for word. War Drummer is no longer associated with SB2 though.
