Just from posts around the web including someone who spoke with Gretchen about it at a party during the finale. Not great sources of course, but like I previously stated, I wouldn't be surprised if they were just covering it up. I had no idea she went public about it, from what I heard, she kept denying it.
But, even if she did write the blogs, I don't remember them being very nasty. Not everyone has to like everyone else, and what she wrote about Romber wasn't all that mean to begin with. In fact, most of the teams were pretty much anti-Romber, and I don't blame them, they had their reality fame, whats the point in letting them onto another show. (what fascinates me about this is that we have not seem the same resistance against Steph and BJ on S11.)
