Here's how to strip bad markup instead of encoding it

   On some forums you might want to remove bad html markup that's not allowed instead of encoding it into text. Here's a mini-plugin to do just that. It also converts <b> into <strong> and <i> into <em>

   It only runs when posts are saved instead of each time they are displayed to keep things at full speed. Posts by Moderators and Administrators are not stripped.

   (note: for now it doesn't obey backticks and will strip inside them)

   <?php
   /*
   Plugin Name: Strip Bad Markup
   Plugin URI: http://bbpress.org/plugins/topic/
   Description: removes tags that are not allowed in posts instead of encoding them
   Author: _ck_
   Author URI: http://bbShowcase.org
   Version: 0.0.1
   */
   
   add_filter('pre_post', 'strip_bad_markup',9);
   
   function strip_bad_markup($text) {
   if (!bb_current_user_can('moderate')) {
   	$tags=bb_allowed_tags(); $tags['br']=true; $tags['p']=true; $tags = implode('|',array_keys($tags));
   	$text=preg_replace(array("/<(\/)?b>/si","/<(\/)?i>/si"),array("<strong>","<em>"),$text);
   	$text=preg_replace("/<\/?(?!($tags)).*?>/sim","", $text);
   }
   return $text;
   }
   
   ?>

   This looks awesome! I am going to try it out tomorrow... I noticed that some nbsp's were being "encoded" in my bbPress installs tonight, and was wondering how I was gonna strip them out. Looking forward to trying this out :-).

   Will report back with results.

   Ah I didn't think of handling  
   But I thought bbpress allowed htmlentities. Maybe only some of them.
