Preventing comment spam
Google, MSN, and other search engines have implemented a new standard that will help reduce comment spam by eliminating the incentive.
Spammers post comment spam to raise their website’s search engine ranking. A new link attribute, rel=”nofollow” will prevent search engines from crediting that site for the link and will not raise its ranking. Supporters of this new standard include LiveJournal, Blogger, Six Apart, Blogger, WordPress, and Flickr.

I’ve implemented it on this site. Note that any URLs in all content will automatically have that attribute added, so posting here won’t raise anyone’s site ranking. I’m also using other spam filters which detects spam and prevents it from appearing, plus I ban the IP address range of spammers.

I thought about just plugging my website here multiple times just to see if it works, but I thought better of it.
Well at least comments will actually be just comments again.
