afk enough and you will be properly punished they are much more laxed since most afks are results of crashes or internet instability and life happening, it's easy to say "report x for afk" but in reality unless they get flamed and rage quit it generally won't be intentional.
there's intentionally feeding and then there's just feeding and being bad, hell I think everyone would've gotten banned atleast once or twice if they punished harshly for feeding. sometimes you just have a bad set, you get focused, you get outplayed, and all you can do it farm and hope to the flying spaghetti monster above you can pull it back which you can't always do sucks gg it's a game tho and thats what many people end up forgetting
plus I have thrown my fair share of shade out but there's a ton more to this than just" oh yeah i said sht gankger then got banned" its obvious you got away with more toxicity but didn't reform right away you got smoted my friend all I'm saying is riot should let you come back a year from now to see if you changed but that's not up to me I'm just a fan of the game riot doesn't undo perma bans unless its a system mistake on their end
sorry man maybe rethink hitting enter and typing on your new account
