I mean, i its enough just to call anyone a noob 3 games arow to get permaban if they reprot you, and this is a fact.
No, that really isn't a fact. If you got permabanned, it wasn't simply a case of you having called people "noob" in three consecutive games. You had to have worked up a sizeable history of misbehavior, having gone through a 10-game and 25-game chat restriction, as well as a 14-day suspension without improvement.
And if you continue to harass players after explicitly told "any further misbehavior will result in a permanent suspension of your account", then you can't really argue that the permanent ban was unmerited.
No one is reviewing any chat, bot just ban without doubt only cuz people report.
If all it took to get an account banned was for it to be reported, my account would have been banned a long time ago.
If you got punished, it was because someone reported you, and the IFS found punishable behavior in the match(es) you were reported in.
Kids just spam reports to everyone who actually said something to them...
And reports get thrown out and ignored if the IFS doesn't find punishable behavior.
...and they can just ban you for trashtalking...
Have you considered that in trashtalking, you're actually crossing the line and breaking the rules?
'Cause that's a thing that's wholly on the table.
