"usually posts a comment" is not sufficient. Dang is human and humans make mistakes. If the system allows somebody to have that kind of power, it should also make it transparent so that we can call them out when it is being abused.
I agree with the parent, if we as a community are going to allow this type of stuff, there needs to be a changelog. We can't rely on good graces of the moderator. It will be abused.
