cleanup-friendica

This is a small cleanup script for Friendica node admins to help with forgotten or dead accounts.

The script does two things:

delete all users after a week that haven't logged in at all and didn't post anything (filter weeks and never.*never)
search for accounts that haven't logged in for 6 months, send them a reminder mail and delete accounts that haven't logged within 7 months

Installation

save the script to your disk where your webserver user or the user running Friendica can access it (e.g. not under /root, maybe /usr/local/bin)
make the script executable (e.g. chown www-data:www-data /path/to/cleanup_friendica.sh && chmod ug+rx /path/to/cleanup_friendica.sh)
create a crontab to execute the script, e.g.: 16 9 2,15 * * /usr/local/bin/cleanup_friendica.sh to execute the script every two weeks
for the first 2 runs you should have the mail text the same and keep the deleting of the user commented out (line 54 in initial commit). After the first 2 runs you should change the first mail text to send out a mail that the account has been deleted because of inactivity and not reacting to the prior sent mails.
change the variables at the begin of the script to your site settings.

you can change the mail command from -b ${siteadmin} -- ${usermail} to -- ${siteadmin} and comment out all lines with bin/console user delete statement for testing runs
before putting this script into production you may want to inform your users via the notify_all addon of the upcoming changes/deletions.
