Please look up how the automated system works before writing a wall of incorrect rage. Again, riot has clarified many times that **number of reports has no effect and nobody will ever be banned based on reports alone.
**
Reports trigger a review, which is first automated, and only done manually if the automated review A; finds something really serious, or B; the issue is something difficult for a computer to deal with, like trolling or feeding.
The automated system is very, very good at detecting straight flaming, harassment and abuse, and surprisingly good at detecting passive-aggressive baiting and veiled harassment.
All it handles is verbal abuse and very obvious intentional feeding, ie 0/17 by 20 minutes, 6 tears.
It may get 'false' positives of a few friends joking around, if someone else on the team was offended enough to report them - which i have seen happen in cases of blatant racist or other hate speech, even intended humorously. Honestly, anyone dumb enough to do that in public should be prepared for someone to take it seriously and take the consequences.
The point of reports is to avoid the above situation in cases where nobody was offended by it or found it unacceptable conduct. If nobody cared, nobody gets punished, even if the system finds something it considers bad conduct(or just bad).
