[MM3-users] deleting a list of spammers from non-member list

Hello to all:

I've studied the following:

https://docs.mailman3.org/projects/mailman/en/latest/src/mailman/commands/do...

mailman shell -l mmlist.domain.ca << EOF | tr , '\012' > nonmember.txt
list(m.nonmembers.members)
EOF

I was able to produce a clean list of 50 non-member email addresses that are spammers.

How would I take this list of non-members and delete them? I was unable to use mailman delmembers
