If you reread the first post in that thread you'll see that the OP was not monitoring the feed very closely. Besides this, that bite is about the equivalent of a skinned knee on a kid. Just because you treat something doesn't make it a life threatening catastrophe. Superficial damage that heals completely after a few sheds doesn't much count in my book.
Now, pictures like that would make acceptable ammunition for your anti-live campaigns. At least it's a "wound" that occurred during a feeding time strike unlike your last choice. Just have to find a way to spin this out of proportion and make it seem like that snake is on death's door.
