If Alibaba is going to establish an official US business presence, they'll have to crack down on the counterfeits, just like eBay does.
In any case, US buyers are better off buying an Epi than one of these counterfeit Gibsons. Less expensive, known seller and comes with a warranty.
IMHO our trademark laws have become way too broad, allowing companies to stifle competition by letting them lock up the shapes of products. OTOH counterfeiting is never okay.
