So, Facebook lets me know if something I reported gets taken down

Ok, but they why don't they send you a message saying, "Thanks summoner! You effort and care in making the community a better place is appreciated. You taking the time to report X for being a dick lead to that player being reviewed and punished."

Or

"Summoner, after looking at your report, we would like you to know that spamming reports is not good. The player in which you reported for intentionally feeding went 3/4. It is not ok to abuse the system. Failure to fix this will result in loss of reporting privileges."

I'm guessing in order to do something like this, though, they would actually have to review a report that isn't verbal abuse (which is literally the only thing they look at).
