When I flag a post for mod attention, a little box pops up that says "Thanks, we'll take a look at it!" or similar. But when I flag a post as spam, there's no such box. In fact, there's no indication that my action was noticed at all. I end up flagging again just to make sure the "You can only flag this post once." box appears, which is an awkward workaround. Can we get some kind of indication that spam flags have been received?
This feature request goes for offensive/abuse/hate speech flags as well, since they apparently have the same no-confirmation behavior.
