I believe the jump from 14 day ban, (2 weeks) to a perma ban is way too drastic.
Perhaps a probationary period.. after 6 month ban.
Here's the thing: Six months is too long of a period for effective punishment. By the time three months have passed, the punished party will likely have forgotten the offense that resulted in the punishment in the first place. If they don't leave outright, they may just start up a new account and forget the old one - and at that point, you may as well just issue a permanent suspension and achieve the same effect.
You can say that the jump from 14-day ban to permanent is drastic...But don't you think getting to the 14-day ban in the first place seems pretty drastic? In most normal cases, you'd have to break the rules at least twice, ignoring a 10-game and a 25-game chat restriction. If you get to the 14-day ban - which is severe enough as is - and still don't get the picture...
Well, how many chances do you really need? If three chances aren't enough, with increasingly severe punishments, then what are the odds you'll get the picture and start reforming after a fourth punishment?
Perhaps link a new account to your old one and allow them to reach a certain level without toxic behaviors or reports for a chance to regain control of their old account.
When Riot permanently bans an account, they've given up on the expectation of the player reforming, and consequently, want that player to leave. They do not want that person playing on that account again - let alone playing League of Legends in general.
Giving players an opportunity to get a permanently banned account again would be welcoming back toxic players, which is not something Riot is going to humor in the near or far future.
It is devastating to lose your account. It's almost discriminatory.. almost.
If you're going to say that getting your account permanently banned due to consistent and belligerent misbehavior is "almost discriminatory", then you can't really say that the discussion you're trying to hold is mature.
Claiming "discrimination" instead of actually accepting that you broke the rules is not mature.
Many people have mental illnesses and are poor, or sad, or hungry.
I have yet to see someone with a mental illness that risks their account's longevity due to misbehavior. Granted, there is likely someone out there that fits such a description, but - I've yet to see them.
As for poor, sad, and hungry...None of those are remotely valid excuses for misbehavior.
They mouth off one too many times and boom. 3 years of work gone.
You'd have to mouth off quite a lot of times to actually get to the 14-day ban. And, again; if you don't get the message by that point, by the point when Riot is literally forcing you to not play their game for a while because your behavior is that bad, you're clearly not going to reform any time soon.
We HAVE to find another way to help people reform.
Let's start with the people who need to reform actually making the effort to do so, instead of trying to find cheap solutions to get banned accounts back.
Even real criminals get parole sometimes, and noone likes criminals.
The metaphorical parole, in this case, is the periods after your chat restriction/suspension are over. You've served your sentence (10-game chat restriction, 25-game chat restriction, 14-day suspension), and you're let out to prove that you can do better and abide by the rules.
If you don't, you get the next punishment tier.
If your last punishment happened to be a 14-day ban, that's it. You're done. The next step after that is a permanent ban.
