Absolutely, Arbitron should rate pirate stations. In fact, I thought there was a Fresno pirate some years back that showed in the Arbitron ratings.
Arbitron has long had a policy that they will not rate operations that are illegal and thus unverifiable. If it is an on-air radio station, their software requires unique call letters and pirates have none. Further, contact with each station is required to verify operating schedules in order to project listening into dayparts, etc.
Today, in the all but two of the top 50 markets, a station has to have a PPM encoder to register in the ratings. Getting one requires that Arbitron know where it is installed as well as the assignment of a unique code. No pirate is going to tell Arbitron where they broadcast from.
Maybe things have changed since the Bush years, but I know that as of a few years ago, the FCC had no tolerance for pirates. Unless of course it's a neo-Nazi pirate, which are allowed to operate for years.
The longest enduring pirates, including the one in Vermont and the one in Berkeley, are/were ultra-liberal.
Most pirates, though, are either "a better blend of music than those commercial stations have" (translation: my iPod playlist) or religious operations that can't or do not want to pay to be on a pay-for-pray station ("We are licensed by a Higher Power.").
Many are very dangerous (I was on an LAX-MIA inbound flight that diverted because the pilot could not hear the tower due to a Kreyole pirate in the vicinity) and interfere with licensed stations.
NJ now has a law similar to that which exists in FL and has assisted in closing several pirates of recent... one on 92.7, within the 54 dbu contour of a liscensed station.
