Why is no one thinking?

I mean every game someone takes your farm even if you are very far behind and most of the time they are also full build what is even more frustrating. Why does no one understand that its so important to get your teammates also strong if you are already pretty fed. The best thing is that they than start to spam your stat and keep saying report top/mid/bot what makes absolutley no sense because they dont let you any kills or farm.
