I understand your motivation. You want to protect people. The title is provoking, I agree. And I think it is intentionally so, because OP trusts (IMO) that people can recognize it. So I don't think it is "bad", or causing harm. But you're right, some protection/caution should be voiced, and you did.
That was the title. Now if you look carefully at the blade, I think all we can say without trying the blade, is, that it really just MAY be a very good Viscaria clone. Structure looks OK, at least the core and outer seems to match the description in the site (Koto, ALC, Limba, Kiri). That still has not much value, it must be tried.
As far as cheap equipment goes, 5 out of 5 rel. cheap (2 European, 3 Chinese) blades I didn't have really positive experience. Perhaps I was not lucky. But for me that Pongori doesn't seem to be worse per-se. Things change...
