In short, adding an attribute to an anchor tag:
rel="nofollow"
will cause participating search engines to not follow/count the link (Google, MSN, and Yahoo! so far).
So anywhere there's a link in user-submitted content you'd add this.
Won't stop the spammers - but at least their efforts will be wasted. Steven - this looks like a job for filter - preg_replace on user submitted links. This could also help drupal.org from being pounded so hard by search engine spiders - restricting them to only follow internal non-comment links. +1 for implementation of this. andre
