Thanks man!! Been looking for this for a while.
Hello!
How do I get the decryption key? 
Anyone can download it, so please remove the link.
I delete the video link temporarily.

All of the MEGA links are down. If anyone has these raw files anymore, I’d be ever grateful.
I made an account as I’m looking for these links too!
I’ve so far only found links for between 2011 and 2015 here:

I would love to see the newer episodes too, but don’t know where else to look.
