Since it was requested the other day, I'm going to make good on my offer of a peer review. Apologies that it took a while to get around to writing this up, but, what can you do?
ez adc: WTF'
ez adc: IS THAT BULLSHIT
ez adc: that fucking minion block
ez adc: that got u the kill
This, I'd like to point out, may potentially be flagged as negativity, though I imagine one-off exclamations like these tend to be regarded the same as "GG EZ" - not enough to warrant a punishment on its own, but likely could contribute to a punishment in the light of other behavior.
ez adc: nah i was running back u idiot
ez adc: report bot
Insults and report-rallying; the first line, you could've been well enough off without calling whomever an idiot. As for the report-rallying; more reports do not increase the likelihood of a punishment, and the IFS only needs one report to trigger a review; there's no real benefit to having more reports filed against a single player, and consequently, report-rallying can be flagged as a form of harassment.
ez adc: xin why do u even bother gnaking this idiot
ez adc: just gank me
ez adc: she doesnt know how to play
ez adc: 0/3
ez adc: with 3 ganks
ez adc: how did this ez even get gold
Insults (calling someone an idiot and exclaiming that they don't know how to play), score-shaming, and passive-aggressive insults ("how did this ez even get gold); none of those behaviors are acceptable.
ez adc: thus league is a fcking joke
ez adc: 1/5 adc
ez adc: 0/4 mid
ez adc: a jg yhat doesnt even gank
ez adc: do u not have cc?
ez adc: she always pushed up
ez adc: ur actually blind if u dont see it
This seems to be the point where the first game's chat log just devolves into negativity, insults, flaming, & arguing.
ez adc: but xin why would i fight
ez adc: u dont provide any damage
ez adc: so no point right
ez adc: report adc ty
And it's capped off with more arguing and another call for reports.
ez adc: agith ff
ez adc: top fed
ez adc: how does a gold nasus feed a silver
ez adc: boosted
ez adc: nvm he trolling
ez adc: hes trollin bro
ez adc: please
ez adc: nasus just admit it
ez adc: ur trolling
ez adc: u see
ez adc: fiora
ez adc: he just flashed for no reason
ez adc: please report
Game 2 starts off pretty quickly with flaming and report-rallying. Regardless of whether or not someone is legitimately trolling, flaming them, calling for reports, & calling for surrenders isn't going to help anything. In fact, if they are trolls, you're basically giving them exactly what they want - a reaction. So by flaming them, you're basically telling them that you're easy pickings and validating their trolling.
It's Internet 101: "Don't feed the troll".
ez adc: lol this kaisa doestn even know how to farm
ez adc: bro ur gold 4
ez adc: you actually have no room to talk
ez adc: anyways report this nasus
ez adc: how am i trolling?
ez adc: dont push lane
ez adc: do you know how to not push?
ez adc: you really think im the one trolling?
ez adc: wow u must have gotten boosted
ez adc: she doesnt know how to farm
The flaming continues, moving on to harassing Kai'Sa, rank-shaming (or, moreover, leveraging rank to insult someone), more report-rallying, and detrimental arguments.
ez adc: the kai sa hits minions
ez adc: instead of jhin
ez adc: and u think im trolling
ez adc: u deserve silver
ez adc: lol stfu xin
ez adc: u cant even jg
ez adc: account buying?
ez adc: boosting
ez adc: HOW DID THIS NASUS LOOSE TO THIS SHIT FIORA
ez adc: and nasus
ez adc: standing in base
ez adc: afk
ez adc: yes go troll some more
ez adc: ty
ez adc: lol xin inting too
ez adc: has ult
ez adc: never uses
And at no point for the rest of Game 2 does it ever get any better. You quite literally spent the entirety of that match flaming and harassing your teammates.
ez adc: WHY CHASE
ez adc: ff 15
Game 3, while shorter, does of course still contain misbehavior, starting with the above negativity. Nobody really wants to hear people exclaim that they want to surrender at 15 - as it were, people rather dislike those who can't commit to a match and readily opt for surrender when things start going sour.
ez adc: panth stop feeding
ez adc: LEARN HOW TO WARD
ez adc: ah yes
ez adc: u fed him
ez adc: 0/4
Harassment, score-shaming, and directed negativity.
ez adc: bro u lost lost hahahaha
ez adc: cause u dont know how to ward
ez adc: morg hasnt hit a single q
And more negativity and harassment both.
Between these three matches, you show a readiness to harass and insult your teammates when they underperform, and a consistent degree of negativity alongside it. And since this was, as you said in your previous post, a few days following your 14-day ban being cleared, this behavior is more than enough to warrant the permanent suspension.
...I didnt swear at the people i only pointed out what their flaws in hope that they could improve and elevate their gameplay.
Unfortunately, the way you went about doing so wasn't actually conducive to them improving. Nobody's going to improve if they're being called "idiot", or being chewed out for "feeding" or being basically yelled at that they need to "LEARN HOW TO WARD"; flaming and harassing players isn't going to help them improve, and, unsurprisingly, there is terminology to describe such a counterproductive method of trying to help others;
Destructive Criticism.
Criticism delivered with the intent to break (people) down, rather than to build them up. While there is certainly something to be said about people needing to know that they're screwing up in order to improve, that's basically all that you were doing. And that's what separates Destructive Criticism from Non-Constructive Criticsm, as well; non-constructive criticism is pointing out issues or flaws; destructive criticism is hammering at them to ill-effect.
If you're wanting to try and help people improve, you're going to have to practice Constructive Criticism; you have to build them up, not break them down. It's one thing to tell someone that they messed up, but it's another thing to help them figure out how to do better next time and encourage them to keep going. That's what constructive criticism is, and it's the most effective form of criticism one can offer.
If people are going to improve and do better, they need encouragement that they can. Calling people "idiots" is not encouraging. They need to have a direction to go in regards to their improvement, they need to know what they should be doing; "Learn to ward" is something so broad and general as to be virtually useless as advice.
There's much more to giving advice and criticism than that, of course; delivery and accepting when people aren't ready to improve are both necessary skills as well, but at the core of it, if your goal is to help others improve, then the biggest problem is the way you're going about it.
