Won't services pop up that mine away, accumulate successful computation tokens, then sell them cheaply to spammers and flooders?
Not as long as the cost of mining per e-mail is higher than the average revenue per e-mail.
- meowface 13y agoTrue, but then you could have potential issues like people running old computers who send 100 or more legitimate emails per day. They won't want to wait 1 - 10 minutes for their computer to spin away every time. They also probably don't want to leave their computer running all night just to get enough tokens for the next day. CAPTCHA is not a nice option, but compared to the alternatives it's probably the best we're going to get.
