You know, there is a rule called "presumed innocence" if you can't prove that someone is telling lies or cheating then he in theory is innocent.

If you can't understand exactly how provably fair system, verifier works why don't you try to investigate it further?

Maybe seek help of some people who are skilled with determining whether verifier is working correctly?

So far you are only appear angry and your only line of attack is: "it is a scam because I say so".
