I have a better idea: purge the Mauthausen committee instead.
They seem to be superlatively unhappy with the state of Austria and the fact that their only field of expertise involves complaining about some of the most inconsequential issues suggests their remaining presence in Austria only emphasises a disturbing kind of masochistic behaviour. The most obvious way to cure this would be to emigrate to somewhere else that would better suit their totalitarian needs, or form their own colony on some godforsaken place in the Antarctic.
If your license plate is not promoting violence, there should be no issue.
Dear God,
chill.
