Not Smart
I worked for Time Warner for many years... I came accross people doing this in Racine, WI... First when they find out and they do have ways... They do a PING test to your DCTs aka cable boxes and find the average repsonse time... then when one is out of range you will get a surprise vist or they will ask you if your services are ok.... Then when they are out by your house they can disconnect cables to neighbors claiming they are doing "cable work" and have boxes rehit and when the DCT doesnt respond they knock on your door again if not already.. Followed by the police getting involved, and corporate, and so on... Eventually you will get a local fine, county citation, state subpeona, and possibly a federal... but definately the first 3... because that is stealing money from the state, county, and local governent... Eventhough you pay for the extra DCT for $10 per month the person who has the box is not upgraded to a digital package...
This is classified under "Theft of a Telecommunications Provider Signal" and does lead to fines court and imprisonment... YES THEY DO PUNISH FIRST TIME OFFENDERS
