Getting mad a valid reason for a chat restriction

So I got a chat restriction for getting mad, again, for the 3rd time to be exact. I'm not gonna lie I get easily mad when my team is performing badly, but that's it, I don't insult anybody, I just talk in an "offensive" way, but I don't feel like I'm insulting anybody or am I? I really can't wrap my head around this, here are some examples:

Nico Nico REEEEE: why enegae? Nico Nico REEEEE: way to throw a game

Nico Nico REEEEE: how Nico Nico REEEEE: dying 9 times? Nico Nico REEEEE: hardly a carry

Nico Nico REEEEE: would you look at that Nico Nico REEEEE: its lamost liek you do nothing if i dont ult them

Nico Nico REEEEE: pick an eaiser adc next time cait Nico Nico REEEEE: why enegage that wtf

I get that this is a pretty offensive talk but I don't think that something like this should be bannable, I honestly don't know, at this point I feel like I can get banned for suggesting what items somebody should buy or telling someone to do something. Am I the problem or is the autoban system or whatever broken?
