Free parking with fake car plate

Just came across this car in Warsawa with a fake car plate. Its a german plate on a polish car, but its 100% invalid because German number plates always need to contain numbers.

Is it common or legal to use fake plates at the back of a car in poland? Is it common?

I mean this is a great way to park in the city center for free…
