Purging deleted users
(These instructions are for a production setup, and may or may not work on a Dreamhack.)
The expunge-user worker purges accounts that have been deleted for at least 60 days. To run it, you also need to run some other commands in concert.
Open up three terminal windows. From $LJHOME, run the following commands, one in each window:
bin/moveuclusterd.pl -v bin/worker/expunge-users -v bin/moveucluster.pl --jobserver=127.0.0.1:2789
