A lot of posts keep reappearing in the moderator queue a few minutes after they've been processed by a moderator. This appears to be caused by users flagging
from /review when they've had the page loaded for a few minutes.
I don't want to discourage anyone from flagging, so can we just disregard those flags with no penalty by suppressing posts from reappearing in the queue? Of course this should only be if they're flagged for the exact same reason as the earlier processed flags, so moderators don't miss any "you made a mistake" flags.
