The distributors who would be most likely to be affected by a GPL violation lawsuit are the distributors who load GPL software onto physical hardware and sell the hardware. For countries that do take copyright violations seriously, it won't be hard to get a court injunction to stop importing the violating product or stop marketing the product.
For all the other distributors we can maintain a blacklist of violating titles, businesses, and countries that we can avoid doing business with. This would be a long-term strategy for dealing with copyright violators that doesn't involve the need for a copyright infringement lawsuit.
