If Q's tripcode had been broken and someone was impersonating Q in that Q&A, don't you think a tripcode switch and mentioning of it would have been one of the first posts out of the gate? Plus, 2235 looks like an endorsement of one of his other Q&A answers. I think people here need to stop living in denial and accept that the Q&A posts were Q even if the answers didn't match up with what you currently believe.  Did you think you knew it all?
