Recently I have been going through the entire pool, cleaning up almost 100 images. Various images not even meeting any of the guidelines really surprised and saddened me. So I was thinking whether the description might be vague or unclear. Especially the first line: "For moments when a cool and calm demeanor is destroyed."
I think this is not entirely clear. The calm/cool or similar demeanor should be destroyed, but with embarrassment, cowering, crying or similar results. As the pool originally formed by Remilia's Charisma Break joke, it should at least result in the mentioned forms.
Example
Just this morning, post #2177319 was added to the pool. Ignoring the fact this is Remilia_Scarlet from Touhou, we can see a tea sipping confident looking girl. In the last panel she breaks into anger (anger vein). The demaenor is destroyed, however, majority of the pool is resulting in the keywords I mentioned above. For this image, this is not the case and thus it is not eligible for the pool.
I intend to extend the first line, but I am lacking the proper descriptive abilities. Naturally, people should use common sense as the guidelines clearly states a 'broken' version is required. And people are encouraged to look at examples. Yet somehow people simply don't or refuse to follow any of the guidelines. So many images added without proper consideration of the guidelines.
Or perhaps I am overthinking this and the pool is fine as it is. I can live with that too.
