What I did is create this little python script that will up vote every video uploaded to Dtube, pinning that video onto my local IPFS.
I don't understand what that part does. What pinning means or rather accomplish. If nobody upvote a dtube post then the video would be hosted past the 7 day mark? Is that why you upvote them, pinning them to your IPFS serve?
Do you know the total volume of all video "hosted" by dtube? Is is bigger than 1TB?
