just from a user experience standpoint, i am not sure I would not do this. As a suggestion have a couple of slots that add ads after certain posts that appear below the posts

see the attached image

if you want to do this - build a plug-in off postbit_display_complete

global $ids; 

$excluded = XX;  // for any usergroups to exclude

if (!is_member_of($vbulletin->userinfo, $excluded) AND $post['postid'] == $ids[POST NUMBER] AND THIS_SCRIPT !== 'private') 
{ 
    $template_hook['postbit_end'] .= '<center>
AD CODE GOES HERE
}

if you think this can help you, use it.
