In the first cooperative move for nearly ten years, the major search engines have unveiled a new indexing command for web authors that they all recognize, one that they hope will help reduce the link and comment spam that plagues many web sites....due to removing the point of doing it in the first place.
The new "nofollow" attribute that can be associated with links was originated as an idea by Google in late 2004 and MSN and Yahoo, as well as major blogging vendors have jumped onboard.
The Nofollow Attribute
The new attribute is called "nofollow" with rel="nofollow" being the format inserted within an anchor tag.
When added to any link, it will effectively serve as a flag to tell the search engines that the link has not been explictly approved by the site owner, and therefore "not follow" it, or not use the referring page's (on your site) Page Rank in any way.
For example, this is how the HTML markup for an ordinary link might look:
<a href="http://www.somedomain.com/page.html">My forums are the best lol lol lol click here!!</a>
This is how the link would look after the nofollow attribute has been added, with the attribute portion shown in bold
<a href="http://www.somedomain.com/page.html" rel="nofollow">My forums are the best lol lol lol click here!!</a>
This would also be acceptable, as order of elements within the anchor tag makes no difference:
<a rel="nofollow" href="http://www.site.com/page.html" >Visit My Page</a>
Once added, the search engines supporting the attribute will understand that the link has not been approved in some way by the site owner.
Think of it as a way to flag to them, "I didn't post this link -- someone else did."

The site that is being linked to will gain nothing from the link, so the whole point of doing it in the first place is removed.
WHAT WILL THIS DO, IN ESSENCE?
This will affect URLs in posts, as well as signatures...anything that goes through the bbcodeparse function as far as I can tell/guess, and will work recursively, or whatever the word is that means 'it will affect all existing posts and signatures'...or it did for me anyway.
Update:
Thanks to Michael Morris and natez0rz for pointing out that using the $post global would be a much better idea.
To change the conditional number of posts, alter
PHP Code:
OR $post['posts'] > 50)
to whatever you like.
It should work with all vB 3.0.x versions, but was tested on 3.0.6.
File to modify: 1
1/ Open your includes/functions_bbcodeparse.php file
Find:
PHP Code:
if ($type == 'url')
{
// standard URL hyperlink
return "<a href=\"$rightlink\" target=\"_blank\">$text</a>";
}
else
{
// email hyperlink (mailto:)
Replace with:
PHP Code:
if ($type == 'url')
{
global $post;
if (is_member_of($post, 6) //Admins are exempt
OR is_member_of($post, 5) //Mods are exempt
OR is_member_of($post, 7) //SuperMods are exempt
OR $post['posts'] > 50) // People with over 50 posts are exempt
{
// standard URL hyperlink
return "<a href=\"$rightlink\" target=\"_blank\">$text</a>";
}
else
{
return "<a href=\"$rightlink\" rel=\"nofollow\" target=\"_blank\">$text</a>";
}
}
else
{
// email hyperlink (mailto:)
2/ Save and Upload.
3/ Relax, safe in the knowledge that spammers linking from your site are doing so for no reason whatsoever.
4/ Edit: exclude staff usergroups and members with over 50 posts.

I'm looking for the same thing. How about completely removing the "hompage" link from contact info?
