There is only one method by which they can catch you for service piracy: waste a pile of money sending a crew out to your neighborhood, and go around disconnecting cables in a binary search, causing major grief for their actual customers. They are never going to do that. The only people who've been convicted have been either paying subscribers that uncapped their authorized modem, or people building businesses around cable modem modification. Both are eminently traceable, and simple service piracy is not in the slightest.
