Goggle Ending Comment Spam
We all knew it was really up to Goggle to stop comment spamming. Well, they have finally provided a solution:
Manni, Halz, and Slashdot beat me to the story:
- If you're a blogger (or a blog reader), you're painfully familiar with people who try to raise their own websites' search engine rankings by submitting linked blog comments like "Visit my discount pharmaceuticals site." This is called comment spam, we don't like it either, and we've been testing a new tag that blocks it. From now on, when Google sees the attribute (rel="nofollow") on hyperlinks, those links won't get any credit when we rank websites in our search results. This isn't a negative vote for the site where the comment was posted; it's just a way to make sure that spammers get no benefit from abusing public areas like blog comments, trackbacks, and referrer lists.

actually, this has been doable for over a year, using a little tiny javascript trick I wrote about in 2003. looks like nobody noticed ;) details here: http://taint.org/2005/01/19/201543a.html

Your javascript idea got similar results but it was not the only one or the best one, it requires Javascript which some people perfer not to use. There were a lot of other places with similar ideas. URL redirects being the most popular till now.
Redirects require a server that handles them. But blogger and other places were providing them. Google's version is much simpler since it will work no matter what and requires no server. Its always been up to Google to fix this, its their PageRank that caused the problem to be so bad. The problem is far from gone, but this is a big step in ending comment spam.
