Google has adopted a standard where any link with the attribute rel=”nofollow” is not spidered by google. Google已经采取了标准的地方有任何联系与属性的rel = “ nofollow ”不是爬行由Google 。

This can effectively dampen the enthusiasm of spammers to spam your comments (comment spam).这可以有效地打击垃圾邮件发送者的积极性，以垃圾邮件您的意见（垃圾评论） 。
It is like throwing the baby with the bathwater.它像投掷婴儿与bathwater 。 In fact if a blogger is averse to people putting in links he can always disallow anchor tags in the comments.事实上，如果一个Blogger是反感的人把在联系，他随时可以禁止锚标记在评论中。
And I don’t think it will have significant impact on reducing comment spam.我不认为它会产生重大影响，减少垃圾评论。 Because automated tools are used for comment spamming and there will always be certain sites which will not implement this.因为自动化的工具是用于评论滥发电邮和都会有某些网站将不会执行。 Also other search engines use link based ranking like Microsoft and things will not change overnight, if they change at all.也有其他的搜索引擎使用基于链接的排名一样，微软和事情不会一夜之间改变，如果他们改变。
This move will only serve Google to improve its search engine ranking, nothing more.此举将不仅服务Google以改善其搜索引擎的排名，没有更多的。

Based on my experience I think that CAPTCHA is the best way (with numerical computation or audio alternatives for visually impaired) to stop comment spam fully.根据我的经验，我认为的Captcha是最好的方式， （与数值计算或音频选择视障人士）停止垃圾评论充分。

I started receiving around 600 comment spams a day.我开始接受约600名评论垃圾邮件1天。 After installing CAPTCHA the number came down to 0 (zero) and has remained ever since!安装后的captcha的人数下降到0 （零）一直以来！ Frankly I don’t think a better alternative is required.坦白说，我不认为更好的选择是必要的。

So to answer the original question - Say no to “nofollow” is my theme.因此，回答原质询-说没有“ n ofollow”是我的主题。
