[Plugin: DRP WordPress User Management] Force user logoff

After banning a member, they’re still logged in and able to use their account. What is the best way to automatically log off users who have been banned? I know that changing their password logs the user off, but I’d like to be able to ban in one swift click. “Ban Users IPs On User Ban” is unchecked.
