Reviews are not being posted to iTunes

I recently launched a podcast on iTunes. For the first several days, people were able to leave reviews. For the past 9-10 days, people are reporting that they are receiving an error message when they try to post a review.

Others have told me that they believe they were successful in submitting a review, but that they are unable to see it. One woman left her review over a week ago and it still is not visible.

Is anyone else having this difficulty?
