are Rioters not allowed to talk during the game ?

i played a game with one of the Rioters and he didn't even do an emo or respond to us or even say hi , are they not allowed to ? first i felt so good to play with someone from riot but then i felt he is like a boot in the game , he was really good but it's not fun to play with people like this please Riot allow them to talk !!!
