Have you ever contacted Riot via support ticket about a particularly problematic player?
I recently had a player who did 6500 total damage in a 55 minute game. He followed our junger around all game, denied me and him as much cs as possible, and claimed he was laughing on skype throughout the whole thing. I think he fits the definition of griefing. I have the replay.gg footage to send to Riot, but I don't want to bother sending in a ticket if I'm just going to get a worthless copy-paste response 10 times in a row (like every time I contact Riot support).
So, my question is have you ever contacted support about a problematic player? How long did it take you to get someone to actually respond to your issue (and not just generic, completely irrelevant copy pastes). Do you think it was effective and worth your time?
