Then why didn't the FCC do anything about all the licensed stations that were splattering up and down the dial and coming through my computer speakers?
Your computer speakers are not a radio. There is NOTHING that can go wrong with a radio transmitter, licensed or otherwise, intentional or inadvertent, that will cause it to come through computer speakers.
If you're hearing a radio station, licensed or otherwise, coming through your computer speakers, your speakers are lacking necessary filtering and shielding.
(this is hardly unusual, I've never seen a set that *was* properly shielded & filtered)
I'm not in Cincinnati & can't 100% guarantee there aren't any stations there splattering up & down the dial. I can say I'm 52 years old and have been a broadcast engineer for 30 years, have visited over 2,100 counties in 48 states and 9 provinces of Canada, and travel *through* Cincinnati at least twice a year. I have heard a station splatter outside its assigned bandwidth precisely *once*. (it lasted for a few hours and covered about 2MHz of the FM band) I've never heard it happen in Cincinnati.
"Splatter up and down the dial" is again almost certainly a shortcoming of your receiver. It's cheaper to make a radio that handles a limited amount of received signal. If you happen to be one of the few who lives near a transmitter... well, that money you saved on a cheap radio is going to be repaid in poor reception.

There are FCC regulations that require stations to address problems resulting from extremely strong signals.
AM: 73.88 requires stations to "...satisfy all reasonable complaints of blanketing interference within the 1V/m contour.". 1V/m is a pretty strong signal! -- I defer to those with AM experience (I'm a TV guy) but I think you can reasonably assume if you live within the Cincinnati city limits, WLW does NOT deliver 1V/m.
FM: 73.318 requires stations to "...satisfy all complaints of blanketing interference..." received during the first year of operation from complainants near the tower. (if a station makes technical changes that require FCC permission, the 1-year clock is reset when those changes go on the air) "near the tower" means the 115dbu contour - more accurately, a radius of 0.245*sqrt(P) miles, where P is the power in kilowatts. For the most powerful FM station in Cincinnati (WAKW 93.3), this distance is 1.7 miles. I don't see any sign WAKW has made any technical changes in the last year though. 73.318 does require stations to provide "technical information and assistance" after the 1-year period.
As "secondchoice" suggests, contacting the station is probably more likely to deliver results than complaining to the FCC.

There is very seldom a pirate that doesn't interfere with another signal that's legitimate.
I would suggest "seldom" is an exaggeration -- a significant majority of the pirates I'm familiar with have selected technical parameters with an aim of not causing any interference. Many of them use parameters that could be licensed as translators.
Unfortunately, a significant minority aren't so careful. There seems to be a new trend in NYC and Miami to use first-adjacents to licensed stations, which is utterly unacceptable.
Any transmitter causes interference over a wider area than that over which it provides service. Just because one can't hear anything on a given frequency, doesn't mean you can operate a transmitter there without interfering with anybody.

IIRC there's now a Jack-in-the-Box fast-food place in the corner of the WLAC lot. (in the major lobe of the array) I have to wonder how much effort it took to get the order speakers working?!
