i honestly don't think it works that way.
Getting chat restricted after 1 toxic game i mean. i think it takes more than 1 game. making the chat restriction a valid one,
Yes it sucks,
Yes those games happen
and yes people are bound to respond to it negatively.
I encourage you to mute them, and just do everything in your power not to respond to them negatively.
There's honestly no winning? What does yelling at a 2/22 Rengar and a 0/14 Azir? The only thing that can happen is your account gets in a situation like this. They won't stop feeding? Feeders aren't like that. Get a stress ball or something :D.
With that said, i think they should make an exception. That hardcore sucks! 2nd to last day of season X_X. if it was up to me i'd only make people ineligible for rewards till the last week of the season. After that it's too close to the end to punish someone for being toxic when they've been good the entire previous year.
[zombie-nunu-tears] Tough luck :(
