I doubt it.

For the same reasons, really. People who already intend to thoroughly go over the input and output to use AI as a tool to help them write a paper would always have had a chance to spot this. People who are in a rush or don’t care about the assignment, it’s easier to overlook.

Also, given the plagiarism punishments out there that also apply to AI, knowing there’s traps at all is a deterrent. Plenty of people would rather get a 0 rather than get expelled in the worst case.

If this went viral enough that it could be considered common knowledge, it would reduce the effectiveness of the trap a bit, sure, but most of these techniques are talked about intentionally, anyway. A teacher would much rather scare would-be cheaters into honesty than get their students expelled for some petty thing. Less paperwork, even if they truly didn’t care about the students.
