[Wordpress] Convert url to junk

Is there a plugin that can convert links in comments into rubbish like http://www.yourdomain.com becomes *********

 

Just moderate your posts. If all you are getting is spam posts that should tell you something. There is no point in trying to convert the URL's.

 

I don't have time to moderate so I would prefer this method =[

 

You can either:

Install a spam blocker, or use Askimet.
Moderate your comments.
Turn your comments off.
Edit your comments.php template files. Delete the website input field from the form.
