Yes, when we made the first one we were far too young, ambitious, and a little reckless to really understand what we were creating. We simply were looking for a way to make mischief and not get caught. We did not take into consideration just how dangerous it could be when we created it, but afterward had the idea to enchant it only to work should the proper incantation be spoken.
I trust you believe that Sirius and I had no malicious intention when we started creating it. All we were wanting to do was to come up with a way to make sure those here were accounted for.
I wonder if perhaps a compromise could be that instead of a map showing where others are, the tracking spells only display the names of those who are here. No locations. Just presence. Like a list.
