Right well upon discussion, we have decided that the review left by Sarah Davis was unsuitable and would have been deleted had anyone requested it (or we had spotted it). So with that in mind we have amended it so that the text is now gone, the stub is still there though so that it is obvious that the new reviews are replying to something that we have removed.
Edit: Just in case any one was wondering as well, the evidence suggests that all the replies are by different users rather than multiple accounts, so well done to the owner for rallying such support and handling it.
