Every once in a while, I notice an alert when I log onto the Stack Exchange:
Wanting to be a good Stack Exchange citizen, I'll often click on that highlighted number, and see what's going on. Sometimes, I'll learn that one of the posts in question has been flagged several times already:
Wow! Four flags in just 42 minutes! At this point, I've found myself wondering: Is there really a need to flag it again?
On one hand, I can see where a moderator might appreciate more flags. After all, when more flags exist, that indicates a fairly solid consensus that the answer has some serious problems.
On the other hand, I've wondered when enough is enough, and there is no need for an additional flag – particularly when there are already more than three.
Lastly, I've wondered if something might happen automatically once the number of flags exceeds a certain threshold. Maybe a fifth flag would auto-delete an answer or something? (If so, I might weigh my decision to flag more carefully, if I know I'm about to cast a "deciding vote," so to speak – perhaps the answer could or should be edited and salvaged instead.)
I was just wondering if there are any preferred practices or considerations or I should know about when doing this kind of housekeeping for the site.
