I am given to understand that moderators cannot turn off all of their abilities automatically. I am asking them, on their honor, to avoid using such tools as part of their play. This is, of course, exactly what they do at present. As your own experiences tell you, it poses no concern. They're a pretty good group of people.
I thought that was good practice, and continue the procedure myself, although I don't think GH specified such a restriction.
