But it isn't cheaper than just mining bitcoins with that same CPU load. This wouldn't prevent spamming, it would just make it unprofitable compared to the alternatives (mining bitcoins).
The JavaScript issue can be gotten around with a browser plugin that does it as well, which would be easy to bundle on the existing Tor browser. JavaScript would still be fine for all the VPN users who get stuck with these things, and the regular users who get them occasionally for whatever reason.
- pfg 11y agoYou're not going to make any significant profit mining bitcoin on a desktop CPU, or any "normal" CPU for that matter. If we assume 5 seconds of CPU time per comment, that's ~17k per day or ~500k per month. The first captcha solving service I found sells 100k solved captchas for $139, so that's about $700 for 500k. As a spammer, I could probably post 5 to 10 times more comments for the same amount of money using your system. This is obviously a very rough estimate, but it should get my point across.
