Exactly. instead they should use the money/time/effort to do some accountability! start by warning everyone that was incompetent enough to use blatantly false data at face value. then, use the fact it was trivial to abuse the system and hope the malicious actores were not sofisticated, use that to try to trace back bad intentions and try to mount a case with a prosecutor. those two things might not be the most efficient, but it will be required with the new system too, so better start with it.
