This is a brand new procedure. There is no evidence property owners will do anything other than evicting the pirate people. You can't say that they "ignore this" as that has not happened yet, even once.Most of them ignore this.
The property owners can't ignore this or they will have a lien filed against the property where the pirate operated. This is an action against the owner of the building or land where illegal transmission originated, not the pirate.
Land owners are not going to sacrifice a whole building to protect a pirate, they will evict the pirate people, present documents to the FCC and ask for a reduction of the fine or removal of the lien.
