We have e-commerce websites that accept payment.
It was in our best interests to study your claim.
Our findings: The barrage of tests, protocols, handshakes,
identification and verification that credit card
companies do, make it well-nigh impossible for anyone
to pull that off by means of a mirrored site. Even
if they succeeded, and that's a big "if", the card 
company would have so richly compensated you that you
would have retired to Copacabana at thirty, instead 
of engaging HTTrack like this.
