Perma ban
Hey there! Shortly speaking, I have just got permanently banned for being toxic on the basis of just one single game. Yeah, I admit that I was pretty much toxic in that game but the case is that I have not been banned before. Moreover, I haven't received any warnings before, thus, there were no chat-bans, 7 or 14 days ban as a warning sign before the permanent one. Thus, I have received a permanent ban right after we striked an enemy Nexus so it took like 30 to 60 seconds to permanently ban me.
Is it a joke or this is how tribunal works and there will be no warnings or such things and the system bans right after you click "Back to lobby" after the game was finished?
Riot, could you please throw some light on the situation?
Thanks in advance.
