Again, that breaks the Seal of Confession.
Let’s imagine a silly situation that George has promised to never ask a guest to remove their shoes in his apartment. One day the landowner says he has to start asking his guests to remove their shoes. So George pits up a sign saying, “Only people who leave their shoes outside may come in.” Yes he never says, “Hey, Judy, please remove your shoes.” but the sign is still breaking his promise to never ask a guest to remove their shoes.
Bringing that back to Confession, such a sign breaks the long held promise of the Seal of Confession. And Church Law is going to keep the Seal of Confession. So any sign saying “We report” violates that Seal.
