Have you looked at Section targeting?

For example, you can downplay the area in your postbit that affects your contextual ads by doing something like this:

<!-- google_ad_section_start(weight=ignore) -->
<div id="postmenu_$post[postid]" align="center">
				<if condition="$show['profile']">
				<a class="bigusername" href="member.php?$session[sessionurl]u=$post[userid]">$post[musername]</a>
				<script type="text/javascript"> vbmenu_register("postmenu_$post[postid]", true); </script>
				<else />
				$post[musername]
				</if>
			</div>
<!-- google_ad_section_end(weight=ignore) -->

Adding the code tells google media bot to ignore this area when matching ads to your site's content. (in this case the username)

You can also emphasize the message area of the postbit to help with the ads.
