How would you know this? In some jurisdictions you can be pulled over and cited for putting a government issued temporary license plate (i.e. one assigned to your vehicle) in the back window instead of the normal mounting spot. At the very least, fake license plates plastered all over a car would raise suspicion, especially if they return information about another vehicle. This is a bad idea all around.
I'm curious if you got cited for this, what they might cite you as violating?
All of which would be registered to that vehicle, which is not what you are talking about doing. Your entire premise is about displaying plates that aren't registered to your vehicle, which will at the very least get you pulled over in most jurisdictions, if not cited.

In Georgia where I live, it would be this:

In short, you can't display a tag on your vehicle that isn't registered to it.
I get that what you are talking about doing is civil disobedience, and I'm not faulting you for that. I'm not a fan of automated license plate readers myself, or more specifically the lack of oversight given that it's usually operated by third party, for-profit companies. I'm just pointing out the flaws in your plan, based on what I know of the law (and I'm not a lawyer, just a former law enforcement staff member).
For the purposes of the experiment I bet you could wrap it in a frame that says "this is not the registration plate for this car" in easy to read letters.
Clearly the safer bet would be enlisting pedestrians or cyclists as the law is silent on either having a car plate visible while they are near street cameras and passing patrol cars.
No, it's pretty clear and straightforward:
"(a) Except as otherwise provided in this chapter, it shall be unlawful:
...
(3) To buy, receive, use, or possess for use on a motor vehicle any license plate not issued for use on such motor vehicle"
But again that's Georgia law, so by all means go ahead and plaster your car with fake license plates and post back here with the results. You might indeed not get a second glance from your local law enforcement. And if you end up causing problems for the ALPRs employed by your local government, all the better. :)
But then, I am of the unpopular opinion that every car should be tracked, they are far too dangerous, and cause far too many accidents for them not to be.
You want to murder someone and get away with it in our society, the best chance you have is killing them with your car.
This is probably illegal in most jurisdictions. For instance, it is definitely illegal in California. Standard licenses plates are 12"x6". 75% size is 9"x4.5". California Regulations (13 CCR Sec. 150.02) requires "facsimile or decorative" plates to be smaller than 9"x3" or larger than 15"x9".
For $10 a month users register their license plate and state, then every month they get a printout of two random plates (at 75% size so as not to be confused with the car's real license plate) which you just stick to the side of your car doors. Of course being on the side of your car no police officer is going to think you're passing it off as your own plate, but every camera trained to detect and record license plates will add a 'hit' to their database right then and there. As more people join more license fuzzing data will be dumped into the databases and eventually all automatically collected license plate data will be useless without manually going through and verifying each sighting by hand, which will make it cost prohibitive.
Hell you could pay pedestrians to walk around with license plates as they go from intersection to intersection. That would be hilarious.
