Report what you find, make threads in manufacturer subs here when you find knives that seem to be fake. No one of us will solve it all, but the more people filing reports, making it harder for sellers to keep good feedback scores, the better the situation gets. The selling platform sites do care about fakes, because it hurts their reputation as well. In a couple years when the Bay starts using its own payment processor then they will have incentive to care again, because they can then be more liable for those sales as an intermediary. Laws change over time, as do company policies. Fakes are a problem in every industry and so companies do want to combat it. What would happen if a company like Nike decided to pull all its products from the big river, and make a public ad campaign about authorized sellers and online sales. That would have an impact that would be noticed.
