Oh the idea sounds very nice! Does that work like a captcha? How would I integrate this into a site?

Didn’t monero hard fork some years ago specifically to prevent this? Always pissed me off

Edit: oh. That’s why this isn’t in the browser…

Oh, that seems like a neat idea. I would like to see it fleshed out a little bit more. But from what I can tell, it’s a neat project.
