Why people like donkey and me rage ( In rank matches )?

Riot you want to know why people like me and donkey rage in rank matches? Take a look at this picture I am going to clip, tell me is this rank system even fare for people who has skills being put WITH THESE TYPE OF PLAYER WASTING 20 MIN OR MORE OF MY TIME?

THIS WAS MY PROMO MATCH AND I HAD THIS GUY WHO WAS PLATINUM <<< My gold promo to platinum almost ruin by this single A-HOLE who you seem to ignore in banning.

Riot your rank system is pure thrash that puts people randomly in a rank position and wish us all luck. HOW IN DEAR NAME WAS THIS GUY A PLATINUM AND NOT BAN YET AFTER 5 MATCHES?

Please note this match was a long time ago I made this post a month or 2 ago and it had over 100 likes but RIOT took it down because it shows how trash their report system for intentional feeders are.

Also these matches are not the only ones that he had, this player had over 9 intentional feeding matches not including mine and still not banned for any of it.

Let this picture for players who rank all the time,let this sink in for you. The other picture is what I feel like every time I get match up with a troll feeder, Riot punching me( Riot trolling me on purpose with these players) was a LCK live stream picture I saved.
