Isn't selling bootleg stuff ALREADY illegal though? I mean, ICE can shut you down for importing ripoff stuff if they find it already - why do we need SOPA/PIPA to make things even more difficult for regular people?
As far as I understand it, if you have a website with a non U.S. domain name and not using a U.S. or U.S.-treaty-based payment system, there is no way to block access to rip-off items (material or digital) to be purchased in the U.S. For material goods, customs have the ability to confiscate these at the borders. There are international treaties in progress, where the U.S. partners with other countries, but the internet is a big, wide-open place and it's easy to move elsewhere or get safe harbour.
(For the record, I believe that only innovation will solve these problems, not suppression).
ICE has no jurisdiction outside the US. As I understand it, they can seize US domains (.com) but not other countries' domains, nor can they force an ISP to block access to a domain. So what legal recourse is there?
