"Now its getting more interesting :) There are a few competitors in the crypto space at the moment for paywalled access to stored content, but I don't see why we couldn't figure out a way to make the idea work in theory even just as an experiment..

I spent some time experimenting with the youtube search api today and theres already a lot of automated spammy marketing videos being churned out daily messing up search results.."

Please do keep me posted with your project!
Good luck!
