There are people who did this for the 2020 elections. They found voters registered to empty lots all over Arizona. Steven Crowder, I think the guys name was.
Not sure on that specific claim, but every one of those type of "fraud claims" I've looked into turn out to be false and full of errors in how they used the information they had to try to prove their claims. An example from Arizona - not sure if the same one as Crowder, not going to watch YT videos on this topic - if it's important enough, write it up and publish it with references and proper proof that can be replicated.
