So is B&N removing samples again?

Someone on Kindleboards posted on 3-17 and reported getting this email from B&N: "Unfortunately, eBooks in the Erotica category are not allowed to have a free sample." The top few erotica books on PubIt seem to be missing samples, but others aren't-- are they working from the top and moving down, or are those books just more extreme than others? I guess we'll see what happens, but based on that email, it doesn't sound promising.
