Shredder Users plugin and RT_System

I was using the Shredder Users plugin for users that don’t own tickets and saw
that RT_System was listed as one of those users. I’ve got a cron job which
eliminates these users as a vast majority of them are created by spam. As a
matter of reassurance, RT_System won’t be removed will it?

Keep up with me and what I’m up to: http://theillien.blogspot.com
