I have recently got some ideas of what may have happened when Machinima closed doors in 2019 after the privatisations of the videos.
I have come up with two ideas:
-Potentially someone who used to work with machinima till 2019 but stayed after everyone left, may still have the password. Or the now defunct Fullscreen still maintains control of the channel and the password is with the former founder/ceo.
-The last person who worked in Machinima after wiping the channel clean off content, still had the password and control over the youtube channel then changed the password to something that is incredibly difficult to remember and purposely forgot the password. Making sure that no one will have control over it.
Both people I mentioned have probably moved on at this point, but I also have heard that Charlie from MoistEsports is still very much interested into getting the channel and giving the original content creators their content back.
The future of the channel is not known at this point in time.
Kind Regards, Mosh
