RT-Shredder remove users with no tickets, exclude system object?

Hello, could someone explain how to exclude the system object/User-1 object
from the rt-shredder command to remove all users with no tickets.

Here are the results I get when I try to run rt-shredder.

root@virt-web2:~# rt-shredder --plugin
"Users=no_tickets,1;status,enabled;replace_relations,Nobody;limit,20"
–sqldump /root/shredder-restore-users3.sql
SQL dump file is '/root/shredder-restore-users3.sql’
Next 13 objects would be deleted:
RT::User-2033 object
RT::User-1 object
RT::User-3009 object
RT::User-20387 object
RT::User-10375 object
RT::User-15815 object
RT::User-20697 object
RT::User-13253 object
RT::User-11873 object
RT::User-16755 object
RT::User-6993 object
RT::User-220 object
RT::User-20373 object
Do you want to proceed? [y/N] y

ERROR: System object was requested for deletion, shredder couldn’t
do that because system would be unusable than.

Thanks
Josh

This is an old post, but I scoured the web and could not find an answer
anywhere. I ran into this in RT 3.8.4 (I know, I should upgrade!).
Here is what I was able to come up with:

Use option “email,*” Like this:

rt-shredder --plugin
"Users=no_tickets,1;status,enabled;email,*;replace_relations,Nobody;limit,20"

This will limit the search to users that have an email address, which should
be all of your spam users but none of your system users (like RT_System).
It’s not a perfect solution but it is working well for me.
