In fact there's a feedback system in place.
On 4 such occasions I got a review.
1st and 2nd:
@Horus took action on Posts reported by me. I got a feedback, "
action has been taken on the post which you had reported"
On the 3rd occasion it was
@Irfan Baloch who sent a review (this is my guess because he was the only mod available online when I had reported a particular post).
4th occasion was the funniest. I had reported one of
@Oscar 's post (one of those days when a mod decides to give a tit for tat reply, just that I thought he could have avoided taking the bait). I got a feedback which read "no action taken. Learn to comprehend".
I had made a similar request to admin,after I realised that there's a review system in place, just that it is used sporadically.
But am assuming mods have enough work load to give a feedback to each and every reported post, so I didn't want to overburden them. If not anything, they work for gratis.
