Network-wide Help Center on Cast Close And Reopen Votes page still says
Close votes age away harmlessly after 4 days if the threshold is not reached. Each new close vote resets the timer, and close votes only start expiring if the question has had 100 views.
Recently we have rewritten close votes aging mechanism. Aging votes and flags starts after 14 days, regardless of view count. So the information on that page is out of date and needs to be updated.
