I completely agree, as soon as there's a valuable product people will find some scam to try and work. I guess it's to be expected.
I haven't read up on Pembient as much as I'd like to, I wonder if a fake rhino horn is a good strategy to combat poaching. I read somewhere that the use of fake/replica shark fins helped to bring an end to shark fin soup in China, so it's not that far fetched.
