So you say you severely punish certain offenses...
At least I remember Riot Games coming out with this 4-pillar creed of offenses that are especially toxic -- toxic enough to be considered suspension/banworthy on the spot.
Correct me if I'm wrong but wouldn't telling a player to "kill yourself with a really big knife" fall under those pillars? Because I reported a player who said that both in-game and through a personal ticket. Support assured me they investigated and took appropriate action. Yet I'm tracking his op.gg and he's been playing for over a week everyday. So obviously he didn't get suspended but likely got slapped on the wrist with some chat restriction which they really don't care about.
It's examples like these that make players lose faith in your Tribunal. And shoot, he spammed the chat with a slew of other things; you'd think he'd have been automatically suspended through your software. But he wasn't.
So again, unless I'm mistaken here, maybe try to enforce your own guidelines more strictly, especially on offenses like these which are actually a big deal and keep players like that out of the game. Granted he wasn't flaming me, but listening to all that nonsense got me irritated. No, muting players isn't such great advice unless your objective is to flat-out remove global/team text chat from the game. Otherwise, I'd have never known about him flaming and obviously he wouldn't have been caught otherwise because your system didn't do jack about it despite him cussing our teammate out like 80% of the time. Pick your poison but at least be consistent.
