I got chat restriction just because I called a 0/14 adc monkey?

So I just played a game last night and met a sivir who can't dodge any morgana's q and died 3 times in a role at bot lane, after that she was flaming and inting the whole game. She literally just push lanes all game and keep give kills to other team. I didn't even say anything rude and I was just saying she's flaming and inting. After that she starts going by how people from other country play on the NA server should get out of this server? I was like wtf you racist monkey? Now riot is giving me a suspension just because of that and not this adc who died 14 times and telling people to get out of the server?
