Comment spam is now futile

The major blogging and search organizations have gotten behind an initiative called nofollow - a simple line of code automatically inserted in comment posts by the blogging tool that tells search engines to ignore Web addresses submitted by spammers solely for the purpose of increasing page rankings.
That means that there is no no incentive for comment spam. They are not going to gain hits or higher rankings. Them spam in futile. At any rate, on this blog, no comment spam gets through anymore thanks to a whole slew of precautions.
