Weird polish censored words

I'm writing this post here because I didn't recieve any answer from Riot on polish boards (nothing new here). And also I had a few responses from other players who agree with me that something is really, really wrong. I understand that you censored polish word "rak" ("cancer"), I know it's overused in bad meaning. But why the hell in every new patch I see more and more normal polish words that are censored on my chat?! Last words I found: "kolo" ("guy" or "tire" or "near"), "daj" ("give" ???? why?), every verb that ENDS on "-chuje" ("dicks"), "szatan" ("satan" - i guess it's also banned word in English, why? It's not abusive word, it's one of the names of devil. Maybe we should ban all names from the Bible?). I bet there are more weird examples but I don't remember them right now and I couldn't find a list. The question is - who is responsible for this?

People say "just turn this off", yeah I think I need to but what is the point of it? If we need to turn it off to understand each other then why it's created in a first place?
