banning players of an online game is a joke

i do not think its ok to flame in game in any sort of game but i believe perm banning someones account is rather harsh why if flaming and cursing swearing is a bannable offence does it allow someone to remove the language filter why not have it on perma this would flter out all the harsh words that the small children like to report everyone for .as you can guess ive just been perma banned but it could of been avoided by having such things in place flaming and venting is sometimes unavoidable its also helps to release some anger why dont riot give the option to restrict our own chat for say 1 week to 30 days and also still allow the said chat to be sent but not visible to other players so people can get this anger out makes the game a little like therapy in a sense but perma banning is stupid all you ever hear in game is report him/her for feeding or whatever if there having a bad game how can you not retaliate to that sometimes also what about ppl with anger issues that have actuall medical problems ppl with adhd or similar who do it without thinking and so on we just ban them also i guess any way riot what do you think and i look forward to the little hitlers jumping on this and saying u fame u deserve bans blah blah blah but in all honesty maybe i do but riot need a better plan because flaming in chat and cheating are the only way to get a ban maybe implement a self restrict or whatever
