Can we get a tip saying "Saying "Easy" is considered negative attitude?"

I still see people say that, and when I tell them "I'm gonna report you for that" they are like "What for?" So I tell them "You said "easy", and that's considered negative attitude". And after I say that, they go on saying "lol thats not true, you're just mad" Like damn, even Riot themselves confirmed that saying "Easy" is reportable.
