Gibson I believe would take action if it were hurting their sales to a great measure. One guy here or there, selling a fake guitar or two, I suspect Gibson wouldn't do anything. Neither would the enforcing arm of the law. I don't think ebay really cares either, makes them money and as far as I know, seeing sellers of fake products doesn't seem to scare people off from using their auction site to buy legit items. Of course it's good that these people get reported. Any deterrent that helps inhibit this sleezy way of making money is good.
