First, this thread has already sold a knife. Second, the old "those people over there are doing much worse than me so this one bad thing doesn't matter" argument is silly.
Giving any sort of attention, especially with links or reviews, to these sort of scammers is helping them. All the cloner threads a while back was just free advertising for the clones while their defenders ignorantly argued in favor of counterfeits.
Best to just avoid this sort of obvious garbage all together. No more attention needed besides possibly a passing, "you see this garbage?" comment. I'll go back to my original point, what if everyone made a thread about some garbage knife ad they saw? BFC would be full of threads like that!
I mean, when you see dog poop on the side of the road, later in the day do you feel the need to tell those around you about said poop?
