Telling a player to "kill theirselves" should automatically trigger a permaban. Period.
It shouldn't be "Oh, if he continues to show unsportsmanlike like behavior, he'll get a 10 game chat restriction, which may I add, you are able to type once per 3 minutes." It should just be a permaban, straight up. Suicide is no laughing matter and you never know how that players life is. They could be going on League to cool off after a stressful day, or may use League as a way to cope with depression. Honest to fucking god, as a guy who's dealt with suicide within my family and through friends, just seeing that in my game's straight up pisses me off. They're literally telling someone else to "end their life", as in, no longer a part of this world, because they didn't follow their instructions.
Those who downvote this thread need to seek mental help because you might consist of sadistic traits. In no way can you argue against my point.
