As others have said, we do not allow negative posts about specific CMs and guides, as there are two sides to every story.
You may post your story, if you wish, without reference to the specific guide or CM.
We also don't allow praise posts to name a specific CM or guide if they broke standard Disney procedure to make a guest happy, as others would then expect the same service...which Disney may not allow a CM or guide to do, except under the most extreme circumstances.
