Sorry, it’s not designed to do that. It filters them out from post content.  The topic description plugin came after the profanity plugin.  

That said, we can add it to our list for future consideration. 

Taking this feature one step further I would say it would be nice if it also filtered out the page title.  I think it’s in the SEO features you can set to display the forum topic title as the page title.  Just a thought 🙂

I did open a ticket that included this. The main problem we have to look at is any knock-on effects from possible html changes. I am actually taking an initial look at this very moment.
