What could/would the CATV company do to come down hard? Would it be anything worse than disconnection of service? I'm not familiar with the laws regarding this, but I'm guessing there could be FCC fines, etc.?

A splitter is a directional coupler (with equal loss on each leg). AND they make directional couplers with different values of attenuation in the "down" leg also.
If you are using a splitter as a downstream combiner, there is little or no energy returned to the upstream. It might be 60 db. down which is negligible.
It has to do with the way directional couplers work and the way energy flows thru the toroidal core.

I would be worried about the signal getting out to the street and going to the neighbors TVs.Thats if there is faulty filtered pole equip passing the signals.like said .It could rise issues with the CC and the authorities and content providers if re transmitting TV programming. I would string another line just for that to be on the safe side.
