If you have the mark and can not see it, presumably you can not know you have it.
Furthermore, if no one that can see it can indicate to you that you have it and there is again, no loophole, then you again can not know you have it.
Since no other way of knowing presents itself, then no one discovered they had the mark.
If no one with the mark came to church the next week, then all cprogrammers were holy and without sin. 0 had the mark. Yeah right.
