Wikipedia:Former administrators/reason/inactive

Inactive: These administrators were desysopped for inactivity per Wikipedia's procedure for desysopping inactive administrators under either of two criteria. Under criterion one, they must have made no edits or logged actions in the past year; after two years of continual inactivity or five years since their last admin action, they are considered long-term inactive). Under criterion 2, they must have made fewer than 100 edits over a 60-month period.

Former administrators desysopped this way may request their rights be restored by a bureaucrat at any time (subject to bureaucrat discretion and a 24-hour wait period to evaluate the circumstances in which they were desysopped).

Active (criterion 1 only)
These former administrators are still considered active by definition of long-term inactivity (they have not gone without an edit or logged action for two consecutive years or their last administrative action was made in the past five years).

Long-term inactive (criterion 1 only)
These former administrators are, by definition, considered long-term inactive (they have gone without an edit or logged action for two consecutive years since their desysop or from years prior to their desysop and the subsequent year after their desysop, or have made no admin actions for five years). The latter cases are marked as such when that is the only reason recorded for their long-term inactivity and in such cases, the column for the time of the last edit/log will refer to the last administrative action. The times of the last edit/log action are not guaranteed to be up-to-date.

Admins desysopped due to having made fewer than 100 edits in five years (criterion 2)
These admins were desysopped because they had made fewer than 100 edits in a five-year period.

Vanished
These long-term inactive former administrators exercised their right to vanish and were desysopped for inactivity, in either order. As with administrators who were desysopped when they vanished, their previous usernames are not stated, and their contributions and logs are not listed, unless they returned to editing after they vanished.

Deceased
These former administrators have died and were later desysopped for inactivity. See also:  Administrators who died in office, Administrators who died after they were desysopped for cause, and Administrators who died after they resigned
