I like the label remakes, particularly the vintage ones that are no longer made and often difficult to find. I don't think there's any problem with reproductions of those. I might have to pick up a pair of reproduction vintage EPI badges.
Regarding the topic in general, look at the auto industry. One can buy a BMW badge (even a real one) and put it on a Ford Tempo. If one cannot discern that the Ford Tempo is not actually a BMW M5, then maybe the buyer doesn't deserve to be saved from their own ignorance. That doesn't mean the seller isn't a crook. But at some point, if people can't help themselves, then maybe they need to learn some lessons the hard way. Do your research. Ask questions.
Where I think things get really messed up is with actual counterfeit products. Counterfeit audio cables are a problem as they're relatively easy to fake but look real, at least to the untrained eye. Fake Furutech products are a major issue. Go to YouTube and you'll find videos showing how to make fake high-end power cables with fake Furutech plug sets.
Again, do your research. Ask questions such as : Do you have the original packaging? Do you have the original receipt or other proof of origin (if they're not an authorized dealer)? If they get defensive or offer excuse after excuse, move on. It's that simple.
