Thanks for reading! The "upvote for discount" scheme is something I really want to implement in a wider way - one day, I'd like to see it as an API that can be applied to anything - for example, selling music on bandcamp, accessing video content via YouTube/LBRY/Netflix... etc..

Development is complicated and expensive, so, doing it by just showing the door person your upvote seems like a way simpler way to test the idea at first. :-)
