Why iam not banned yet after feed and flame new players?

After afk flaming and feed more than 10 games the only punishments that i get is 2 game chat restriction even after a lot of them told me that they will send screentshot and report me xD (yeah this happen even in -30 lvl), when in one of my mains playing rankeds i get a ban of 14 days after 1 game feeding and 1 chat restriction.

My question is riot dont care about new players? (This is not the first time that i create a new acc and dont get ban even after feed more than 20 games in a row)

This is my match history

I even have a premade that i did after flame him and he report me every game and iam still not banned WTF?

I literally flame every single player post and before the game and then i ask them for duo so they can flame me in voice chat and report me in all my games and a lot of them accept it,

the last games i was with my premade and 3 randoms than i flame, i feed the game and insult them and they wanted kick me but they didn't LOL
