A user was unexpectedly deactivated after years of activity, despite regular API usage. carlokok initially mistook the status as “staged” but clarified it was deactivation. jomaxro suggested the likely cause: automatic deactivation of inactive admin accounts after one year of no site login. carlokok confirmed the user was an API-only admin and disabled the auto-deactivation feature. hosna reported a similar issue affecting API-based signups and urgently requested disabling the behavior. carlokok and dax pointed to the site setting invalidate inactive admin email after days, which defaults to 365 days — the root cause of the automatic deactivation. Users are advised to adjust this setting if API-only admin accounts must remain active without login activity.
Without knowing some additional data about the user, my best guess is that they hadn’t been seen on the site for a year, and are an admin, and as such were automatically deactivated. Does that sound right?
