Alternative means of propagation

Does anyone here have any experience with carrier current or leaky feeders?
Since I live about half a mile away from an automatic frequency monitoring station there is a good chance that vans with antennas will start appearing in front of my house as soon as i start broadcasting so i am thinking about innovative ways to broadcast.
My first idea is just plugging a coax cable from transmitter into a cable tv outlet. Cable tv in my area recently stopped broadcasting fm radio on selected frequencies probably with a plan to upgrade upload internet speeds in the future, so with some luck and shitty installations there are probably a lot of leaky cables that can function as antennas nearby. I live in a row of about 5 houses that have cable just pulled through our lofts and then from the first house presumably underground to the cable plant so if anyone comes knocking i am just as likely suspect as all of my neighbours. I am not sure if they are even subscibed to cable, since i am not, but i still have outlets from the previous tenant.
In the best case scenario that i can imagine, cable plant has some filters but they probably allow upstream traffic for the cable modems on my selected frequencies and even boost it and since my signal will presumably be stronger than it is expected from cable modems the filters that limit downstream on selected frequencies will let some through.
This link is pretty much the only thing that even remotely resembles my idea that i can find and in my country i guess it will probably be considered hacking so the worst case scenario is probably prison time for me.
But this does not deter me enough, so I have a couple of questions, if anyone can answer:
1. Is it possible to destroy my neighbours (connected on the same coax) tvs/cable modems/any other electronics that way?
2. Will my neighbours hear my broadcast whenever they turn their tvs on, no matter which frequency they use?
3. Will i limit upload speeds or even prevent upload for everyone connected on the same plant?
4. Will i fry the cable plant?
5. Considering there is at least 200 ft of cable from my transmitter to the cable plant, do i have to put my transmitter in some kind of faraday cage so the signal that leaks from my transmitter and transmitter to cable connection wont be stronger than the signal that leaks from the cable plant?
6. Is my idea insane?
7. Is there anything else i should consider?
My other ideas consist of using some kind of carrier current, but is that even possible with fm and outside your own house? Something like PLC? I should probably avoid using the phone line in any way right?
