I don't know... I was following it too. The last post was by someone saying that the DIS doesn't allow "personal attacks on CMs", which had NOT happened in the thread. All I can think of is that the bride decided to delete it because she wanted to focus on her wedding and just cut out the negativity from it having gone viral, or someone MISREPRESENTED what was in there and it was deleted. If the latter is the case, that is an appalling cover-up.
Im guessing that she got a resolution that they were happy with and part of the conditions was to have this shut down. So she requested it.
