I do something similar to stop search engines (guests) from indexing members usernames from forum posts, while leaving the forums visible for earch engines to index the posts content

In my case I added the code to do this to forumdisplay.php

The loop handling the display of forum threads starts

while ($thread = $db->fetch_array($threads))

It executes once for each post in the thread


This would be a good point to enter your code. Here is mine (which reverses the characters in usernames and sets them all to lowercase) you could do something similar to replace your unwanted URLs with blank space, or some other text like 'veiwable only to members'

I determine if a user is guest from if (!$show['member'])

		while ($thread = $db->fetch_array($threads))
		{ // AND $counter++ < $perpage)
			// jumble up poster and last poster name for guests/search engines
			if (!$show['member'])
			{
				$thread['postusername'] = strtolower(strrev($thread['postusername']));
				$thread['lastposter'] = strtolower(strrev($thread['lastposter']));
			}

Hope that helps
