Is it possible to be perma banned if you didn't even talk in chat?

I got a reform card and since then i barely talk maybe 1 word but never anything negative ((quoting what teanmate said does not count as saying it myself i think ("useless champ") ) Even when i get mass flammed i just ignore and say positive things or neutral (more neutral than positive) like for example, it's better for me to go x lane than that because i have more cc and that. I end up the game almost every game reporting someone either i win or loose i always report someone if is flamming me or someone or my team or enemy team. That's why i barely talk in chat. My question is if they report me for they think inting can i get perma ban? Even if i have positive score? Edit: I send a ticket to riot and they said this []
