You could have left your post intact. First of all, you are using your "number" instead of your username. Second, I don't think there was anything in your post that would lead someone to identify you --- not unless you told everyone you know that you were going to post in CZ. All that said, I do understand being careful not to give out too many details that could lead someone to figure out who you were. But again, I don't think that you did that.
