Why did I get a chat ban for this?

Game 1 In-Game Jackman121: HAHAHAHAHA SO FUN Jackman121: yeah so bot is hard countered Jackman121: if no ganks tower going Jackman121: kk gg Jackman121: tell jungler beforehand and still eve comes first Jackman121: thats just poor jungling Jackman121: nothing i can do there Jackman121: no, asked jungler for help Jackman121: ah yeah Jackman121: hard counter no jungler Jackman121: feels bad Jackman121: kha probably one of those junglers that thinks "ganking is optional" then loses Jackman121: not ganking any lanes for 7 minutes? Jackman121: that should be reportable in this meta Jackman121: bring back the report for low skill lol Jackman121: he might as well just afk if he isnt ganking Jackman121: yeah gg Jackman121: 4v5 no jungle Jackman121: imo riot has given the jungler waaaaay too much influence over the game Jackman121: junglers dont play around their laners, laners have to play around junglers its so dumb Jackman121: junglers having too much power doesnt mean i enjoy playing jungler Jackman121: just means laners have too little control Jackman121: yep that seems balance Jackman121: see how dumb that is Jackman121: you can literally 2v1 because your jungler ganked and mine didnt Jackman121: we lost first blood cus we had to leash and you guys didnt Jackman121: again, playing around the jungler Jackman121: shouldnt kha have ganked? Jackman121: i just want the game to be more fair Jackman121: if you get ganks and i dont that isnt fair Jackman121: more like even fucking once lol Jackman121: 8/1 leblanc that i have never died to can one shot me Jackman121: lol ok Jackman121: what did kha even do this ggame Jackman121: i just feel that if one jungler ganks and the other doesnt it totally ruins the game Jackman121: if kha had ganked i probably wouldnt be 0/7 tho Jackman121: probably more like 3/33 Jackman121: lol seems balance Jackman121: lol got it Post-Game Jackman121: not ganking = afk imo Jackman121: bot sat under my tower all game and jungler still didnt come Jackman121: thats just troll

While I was clearly telling my jungler that he was playing badly, how in the world is this considered toxic/ chat ban worthy? Riot doesn't do anything about inting, trolling and ragequiting, but I get punished for this? Not once do I ever level an ad hominem at any one. What is going on here?
