Posting Problem

I've just set up my new career story. I've tried posting my first update as a comment twice now and it has disappeared both times. The post shows up when I click the preview button, but when I click post it does not appear on the story and has completely gone. I've done this twice now, any ideas?

UPDATE: Appears to have sorted itself out now. Only took an hour XD

Did it possibly have Chinese characters in? That's the only thing that I can think of that would cause that (to help fight spam)
