where in the summoner code is this?!
Spamming is reportable and based on two games you had people, both sides report you for spamming an in game emote. At no point should a player need to adjust their settings to avoid spammers.
If you are disrupting that many players its obvious you are being troublesome. Punishment justified. Please refrain from spamming your taunt/jokes/laughs then you won't be banned.
