Auto-closing inactive tickets
Close tickets that went silent after a set number of hours, and what the member sees.
Setting
auto_close_hours on Ticket Configuration or /ticketsetup settings. 0 turns it off. The bot sweeps open tickets periodically and closes any whose last message is older than the limit, with the close reason "Auto-closed after N inactive hour(s)". The transcript, rating DM and log entry happen as for a manual close.
Picking a number
Support with fast replies: 24 to 48 hours. Sales tickets where buyers wait for payday: 72 hours or more. Remember the timer counts from the last message by anyone, so a staff "any update?" restarts it. Use /ticket remind to DM the member before it expires if the ticket matters.
What it will not do
It does not close tickets that are claimed and locked differently from others; every open ticket is treated the same. It does not warn before closing; post a message yourself or set a longer limit. Members can open a new ticket afterwards, subject to max_open_per_user.
