Large American internet service providers these days tend to operate under a "six strikes" approach to piracy -- they'll warn you if they catch copyright violations, but it's unlikely that you'll get the boot. However, that isn't good enough for BMG or Round Hill Music. The two music publishers have sued Cox Communications for allegedly refusing to forward notices demanding settlements for copyright violations. According to the claim, the cable giant went out of its way to treat these messages like junk mail, letting about 200,000 "repeat infringers" go scot-free. If the court agrees that Cox knowingly looked the other way, it could be in trouble. The Digital Millennium Copyright Act requires that networks have a policy for cutting off unrepentant pirates, and the lawsuit suggests that Cox doesn't respect that rule.
