Re^9: (OT) nofollow considered harmful

Guess what? I don't want spam to exist either. I thought that's why we were looking for ways to lessen it; I don't quite see how your frustration at spam figures as part of your argument against nofollow. That it does not provide you with immediate satisfaction is unfortunate, but hardly proof of its worthlessness. Would you reject antibiotic treatment for an ear infection just because it isn't instantaneous? If you were a doctor, would you not prescribe liniment for a patient with chronic arthritis because it isn't a complete cure?

I didn't realize you were talking about hashcash in weblogs. Why do you think it is 100% reliable there and not in email? What makes you think Javascript is not an imminent part of the deployment problem?

One of the first attempts at implementations of hashcash for weblogs is just broken. That is, the person who made it didn't understand what hashcash is at all; the whole point is that stamps are somewhat expensive to create. Basically, they just have a challenge-response system with no crypto at all, which is only a little more difficult for the spammer to overcome than learning a new blog post format.

Granted, a solution that does implement hashcash can spring up any time now. Good, let it. Then you have to deal with the Javascript problem. Which is quite similar to the deployment problem of hashcash on other platforms such as email. Or, of course, you could reject clients that don't play along, but you know, you could also charge them $50 a comment and be done with it.

Those unattended blogs, they won't be implementing hashcash, either, but I guess that's not your problem.

I am not frustrated about nofollow's lack of immediate value at all. I don't personally care about spammed search results because I do very little business on the web and don't consult generic web search engines when I do anyway. My queries do not tend to include keywords that draw spam and the things I'm looking for are easily distinguished from spam. But I care very much about spam on my web log, because it requires me to waste my time dealing with the excrement of reckless wankers. nofollow will never change that. Hashcash is more reliable on web logs than email because all legit visitors will receive my hashcash implementation. No, it's not a perfect defense because some of them will not run it, but I can expect far more correspondents to send hashcash with their web log comments than with their email, and it's easy to design a fallback test that puts comments in a moderation queue. The effect is that only legit comments from people without an enabled Javascript interpreter and manually posted spam require my attention. That's a huge difference in wasted time I can have right here and now. Oh, and it helps search engines, too. Makeshifts last the longest.	[reply]

They are not mutually exclusive, of course. By all means, I encourage you to put forth your hashcash implementation. (I'm glad you realize you will need a moderation queue though, because for a minute there it looked like you wanted to reject any proposal that included one.)	[reply]
