Complaint Banned for 24 hours for using an illicit word

[Flaccus]

Today I was banned by mexicat for using the "r" word. It was maybe my second or third ever SS13 game, I literally didn't know how to drink for example. A guy asked me to throw him on a desk. I was very nervous as he tried telling me to change my intent and whatnot I didn't understand half the words he said so I said something like "Sorry, I'm r------" and ran away. Now, English isn't my first language, I'm from Eastern Europe and never heard of this word being a "slur" or "offensive" and that as such shouldn't be spoken. That said I accept the rules and aim to follow them. An admin, later in the round told me that I shouldn't use the word and I apologized and haven't used it since. All this happened I think over two months ago so why was I banned today?
