Let's talk about toxic premades

Just had the displeasure of playing with a 4 stack (normal, not flex queue). I was not doing well and I was having lag spikes which I was noticeably getting pissed about, as they were causing me to die stupidly. My teammates then started encouraging me to afk and making stabs at me for being bad, complaining about lag, etc for literally the entirety of the game. I muted them, but they figured it out and started doing the "Ahri: alive" ping spam in chat. So I had to mute that, too. For 4 fucking players. This literally defeats the purpose of the game. I had absolutely no way to engage socially in fucking social environment due solely to a toxic af premade. This should warrant much stricter and more sensitive punishment (ie first offense temp ban, second offense permaban) for ALL GUILTY PARTIES, and perhaps even a forced disbandment of the club (if applicable). This is far from the first time this exact situation has happened, and it's literally the worst thing I have endured in this game. People like this will ALWAYS report you, and if you so much as spoke out against them, you'll usually end up with a strike against your account (or perhaps a punishment if your account has previously been flagged). Riot needs to do something about this. Solo players literally have 0 agency in a situation like this, and the future of their accounts very well may hang in the balance.
