Report system too flawed

Here's one of the example that happened to me last game:

I'm level 18 so I play with other low levels right but my friend taught me how to play and I know that on a support you gotta control vision have wards pinks (especially against rengar in which it was the case last game). Now my support sona rushes morellonomicon (didn't even upgrade her support item to tier 2) because you know low levels sonas think supporting means just poking for damage in lane. Now i got ganked by rengar many times and my jungler baited me into fight many time in wich i got hard cc'd ashe arrow leona etc etc at that point I am behind and i just wanna farm. Zac dives all the way to 2nd tier turret at 7 minutes and starts blaming me for not following up which resulted in a snowball of hatred which got me a report by him. Later that game I am farming up other lanes so I can catch up into the game and they decide to fight and die and sona starts blaming me as well (also got 1 shot by rengar a couple of times since she refused to follow me and i was playing kalista so imagine the struggle of not having the stats of Oathsworn with you) now those 2 were mad at their mistakes but wanted someone to blame so obviously they target me with their insults and i muted them end of the story. But because of their mistakes and their tilt they still ended up reporting me and got one person on the other team to report me as well and we know that it's an automatic system so basically i might get chat restrictions and lose hextech drop rates because of things that are completely out of my hands and not my fault. Can we please do something so that people stop abusing the report system just because they are mad for losing and dellusional as to why since it's mostly because of them. Not only they make us lose with their tilt but get us in this toxic wheel of reports and there are many people i have seen on streams etc get punished when games were the reports were completely out of their hands and not their fault. Like I am not responsible if you don't understand that for example nunu is better at securing objectives and since you are low level you play for kills you get mad because nunu decides to focus on drags and you lose your lane (1v1) and start blaming nunu and report him just cause you're mad over your own mistakes that you project this hatred on others and we DO get punished because of them that is completely extremely flawed. Even if we report them back. Report system has to change so it doesn't get abused by these people it's too easy to press on the report button at the end of the game just to cause evil.
