The main reason for the non-JS solution is because a lot of people in communities around me, me included, generally block JS in their browsers, and I thought it'd be cool to have a non-JS PoW solution.

To be honest I would prefer if this could be computed with a simple shell script, but calling sha256sum in a loop is ridiculously slow. I might consider other methods of doing proof of work in the future (IIRC it's possible with argon2).

I agree. I also usually disable JavaScripts in the browser, and I think it is a good idea what you did with this. (Some users also may be using a browser without JavaScripts, so it is helpful with that too.)

I also agree that a simple shell script would probably be better, although nevertheless it is explained and someone could implement their own if they want to do, so it is good enough for now.
