[rt-users] rt-shredder Users plugin deletes tickets?

[Howard Jones]

I've just upgraded to RT 3.8.7 from 3.6.5, and I'm catching up on my 
shredding.

Over the weekend I shredded 20000 or so deleted tickets (spam mainly), 
and today I went to start on the users. This has never really worked 
well before, so we have about 60k users, and at most 1000 of them are 
active.

So I created a user called placeholder, made them privileged and made 
sure they are the requestor on a long-running ticket. Then...

./rt-shredder --plugin 
'Users=status,enabled;replace_relations,placeholder;no_tickets,true;member_of,unprivileged;limit,100'

Why does the Users plugin delete tickets? Surely it should only be 
deleting users that have no tickets (no_tickets, true)?

Thanks for any illumination...
