连接当中多了一种属性。这样搜索引擎就知道这个连接不作为参考,久而久之就没有spammer做这种事情了。

抵制垃圾留言与企业责任
很多blogger最近一段时间都饱受垃圾留言之苦。这些垃圾留言,大多数都带有外部链接,通过大量发送垃圾留言,可以提高他们网站的搜索引擎排名。这些垃圾留 言者感兴趣的,不是你的blog内容,而是他们自己网站的搜索引擎排名。所以,要解决垃圾留言问题,搜索引擎必须拒绝对这些留言中的链接计算rank值。现在, Google开始动作了。

Google为链接增加了一个新的属性:rel="nofollow",并开始对这一属性进行测试。Google的这一提议得到了包括雅虎搜索、MSN搜索和一 大批blog服务商的支持。Donews
Blog也将支持这一属性。以后,在Donews
Blog上发送垃圾留言的人,将不会得到任何好处,他们留下的链接不会被计算到搜索引擎排名中。

这一属性很简单,按Google的说法,是这样做的:

Visit my <a href="http://www.example.com/">discount pharmaceuticals</a>
site.

这个留言会被转换成

Visit my <a href="http://www.example.com/" rel="nofollow">discount
pharmaceuticals</a> site.

rel="nofollow"这一属性,不但作用于blog,在任何用户可以留下链接的地方,都可以使用这一属性。

我希望,百度尽快支持这一属性,加入到全球抵制垃圾留言的共同行动中。不让作恶者从作恶中得到好处,就是为善。

看到一些blog的留言簿,还有一种办法,在正式提交wiki修改的时候加上验证码,这样应该可以防止很多spam吧?

这是用来阻止机器人的好方法。
但我认为在wiki收效不大,因为我看到wiki的spam大部分都是人工加入的(因为他们会选择性的删除竞争者的spam,或者隐藏spam在已有的内容中~ ~)。此外,CooCooWakka本身的版本冲突校验机制使得大部分post机器人都无法工作。

那还是nofollow比较好,而且做起来比较简单。
