you know, nobody questions that the "toxicity" i.e. verbal abuse should be addressed in some form, but riot simply does it both very tough and very clumsily
permabans and 14 day long bans aren't a common instrument to address it, it's usually the stuff vs those who cheat, actively ruin multiple games or with whom the company in question has some financial disputes (chargebacks, sometimes even fraud etc). it's ridiculous how little permaban is worth in the league comparing to the most of the games. it's a pretty usual case when somebody, after a certain amount of reports against them (and everybody who plays this game is reported) was reached, is chat restricted or banned for stuff like "f yourself" (pretty often said when they were provoked) or even for "typing too much" (c) one rioter answering a guy who didn't type a single insult why he was banned, and then they are permabanned because when their term ended they said somebody that they did a bad move or something like that, were reported again and this time it didn't need a lot of reports to ban and permaban them. it's not something which i invented btw, it's how it happens. i usually suggest people who were banned once to keep full silence for a while when they play again not saying even "hi" to protect themselves. how people try to justify this crap would be beyond me unless i remembered that most of people are sheep, that's on a side note.
so, this system firstly is very tough to a few people who certainly didn't deserve such a severe punishment and is very clumsy because it allows those who are actually "toxic" to insult people for a long time till they get the needed amount of reports to be banned, at least if they avoid the tabooed words (mostly sex and race related ones). speaking of the tabooed words, a few people are banned for quoting insults in their address ("he called me n-----!"), because the bot considers it as them using the same word themselves... very silly, indeed
now, several people did tests that if you keep silent you can ruin hundreds of even ranked matches with inting, afking, trolling and you will not be banned, because the focus of this whole system is the verbal abuse. meantime those, who are annoyed at you and bm you for trolling, can be banned if you report them. it is completely unacceptable. it should be vice versa, those who troll the games should be banned and the proper punishment for verbal abuse it should be chat restrictions, maybe even permanent chat restrictions, but not bans, the more so permabans.
do you realize that you can be way more free in what you can say when you are talking on this forum than when you are talking in the game? we can call each other names here, the more so we can call each other bad players etc, without any risk to lose our account, and usually without any risk to even get our posts deleted, meantime speaking in the game we are at risk to be banned for saying the very same stuff. it's weird and very wrong, the in-game chat punishments should be similar to the forum ones i.e. it should be chat restrictions with limited pings per minute and stuff
