IR's curtness at this point could be due to a quiet period. Or, it could reflect the fact that they have learned that people here are reporting the specifics of their communications, and it makes them nervous. I know if I was in IR I would feel a little uneasy about every detail of my conversations being reported on a message board, even if I was doing nothing wrong. For example, I would be worried that someone may misinterpret, misquote, or incorrectly describe my statements.
