need someone from riot for some advice

if i wanted to report a player for constantly using all chat to spam them report our team member, at the end of the match how can i make sure they the most adequate report and punishment is possible? as a person who doesn't use chat much now anymore, it pisses me off that when i dont even chat RIOT allows people to SPAM during gameplay asking for reports! This needs to get fking fixed or block the users that use report even in their sentences. You are allowed to decide what terms are appropriate to say during gameplay and having a selfish teammate spamming report report report should be banned for ruining the enviornment of the game. so what's the answer?
