Mentality on PBE and Feeding (URF)

Can we start banning accounts who openly feed every game. Just had a game under 12 minutes, where my top lane died 13 times before their turret exploded (combined) and died a total of 40 times over the course of a 12 minute game. I do not understand how this is not griefing and people are not being punished for this. They would spawn and literally throw themselves at the enemy for dying. When I had asked the enemy report them for feeding, I was met with laughter and comments such as, "It's just PBE calm down kid have fun!!" The mentality of PBE needs to seriously change or people need to start losing their accounts for it. Does RIOT even monitor these things? Or do they care about their spreadsheets more than actual people who want to play/test stuff out.
