That's true but there's a point at which a mistake is not excusable. When it's not even a good fake, it's one with glaring mistakes that should be obvious to fashionphile.
Here's an example of a bag that could still be fake and an excusable mistake if it was, but at least it's in the correct font.
Versus this one with "PARIS" in helvetica which is a font Dior has never ever used. Off the bat it's a fake. And that's basically all fashionphile does, they don't produce any products themselves. They're not doing the one job people count on them for: at the very least don't sell obvious fakes!
