I'd like to do this, so that "spam comments" don't give them any juice. Is it possible to adjust things so this happens to posts made by users? (But perhaps NOT to those posted by admin or perhaps not to links that are posted with our own URL?) Thanks >>>>> Q: How does a link change? A: Any link that a user can create on your site automatically gets a new "nofollow" attribute. So if a blog spammer previously added a comment like Visit my <a href="http://www.example.com/">discount pharmaceuticals</a> site. That comment would be transformed to Visit my <a href="http://www.example.com/" rel="nofollow">discount pharmaceuticals</a> site. Q: What types of links should get this attribute? A: We encourage you to use the rel="nofollow" attribute anywhere that users can add links by themselves, including within comments, trackbacks, and referrer lists. Comment areas receive the most attention, but securing every location where someone can add a link is the way to keep spammers at bay.

It's straight forward... simple as can be... find the lines, add the rel comment, in the url tag... You see: // Link regexes here
$body = preg_replace( "#\[url\](https|http|ftp)://([^\"\[\]<>]+?)\[/url]#i", '<a href="\1://\2" target="_blank">\1://\2</a>',$body );
$body = preg_replace( "#\[url\]([^\"\[\]<>]+?)\[/url\]#i", '<a href="http://\1" target="_blank">\1</a>',$body );
$body = preg_replace( "#\[url=(https|http|ftp)://([^\"\[\]<> ]+?)\](.+?)\[/url]#i", '<a href="\1://\2" target="_blank">\3</a>',$body);
$body = preg_replace("#(<br />|^|\s)(http|https|ftp)://([^<\"\[\s]+)(\.|\,|\?|\)|\s)?#i", '\1<a href="\2://\3" target="_blank">\2://\3</a>\4',$body);
$body = preg_replace( "#(<br />|^|\s)(www\.[^<\"\[\s]+)(\.|\,|\?|\)|\s)?#i", '\1<a href="http://\2" target="_blank">http://\2</a>\3',$body );You do: // Link regexes here
$body = preg_replace( "#\[url\](https|http|ftp)://([^\"\[\]<>]+?)\[/url]#i", '<a href="\1://\2" target="_blank">\1://\2</a>',$body );
$body = preg_replace( "#\[url\]([^\"\[\]<>]+?)\[/url\]#i", '<a href="http://\1" rel="nofollow" target="_blank">\1</a>',$body );
$body = preg_replace( "#\[url=(https|http|ftp)://([^\"\[\]<> ]+?)\](.+?)\[/url]#i", '<a href="\1://\2" rel="nofollow" target="_blank">\3</a>',$body);
$body = preg_replace("#(<br />|^|\s)(http|https|ftp)://([^<\"\[\s]+)(\.|\,|\?|\)|\s)?#i", '\1<a href="\2://\3" rel="nofollow" target="_blank">\2://\3</a>\4',$body);
$body = preg_replace( "#(<br />|^|\s)(www\.[^<\"\[\s]+)(\.|\,|\?|\)|\s)?#i", '\1<a href="http://\2" rel="nofollow" target="_blank">http://\2</a>\3',$body );
