You were asked to stop, at which point you then decided to continue. You were kicked, and then when you logged back in, you were disrespectful to an OP (2crzy4uall) and then not even 5 minutes later, decided to spam chat with irrelevance and the emoticon again. This was not a matter of not knowing what was and was not appropriate.
The ban is only for 1 day; you'll be able to join us again this evening at the same time you were removed from the server. This is a warning though: You've already accumulated 4 bans. You could already have been permanently banned. One more bannable offense, and you WILL be permanently banned.
