What's going wrong with banhammer and chat logs/Adc sucks now?

I have been a League player for 3.5 seasons and recently got 3 permabans in just a matter of 2 months.1 of them was deserved to happen so Im going to talk about the rest.Chat logs including garbage like "wait team need 50g dont fight" or "lets invade blitz can grab" or shit like that.Especially on permaban number 3 out of all the chat logs the only thing that was toxic was "report dianna losing her lane and trolling therefore".So can somebody tell me how the chat logs are being pushed towards us?I mean is it some automated shit because I have talked with many people and we concluded that 60-70% of chat logs aint flame or what.

As for the adc shit.I remember myself playing adc since i started League.Why the fuck did riot shit on adc's.I mean you pretty much cant help at all when assasins arent afraid of tanks and just jump 1v5 and pick some kills.Whats the point of making a carry role that useless?Im a draven one trick way before tyler1 got famous and after these permabans im just running it down mid every single game and not getting any kind of punishment.Thats a reason for permaban not the crap i get in chat logs. Opinions lads on both shit
