In other words:
1. If it was stolen credit card scam no legit winner would get the prize anyway. CH would try to nominate his alter ego designer.
2. If contest was a hoax to get free designs it would be refunded anyway later on after even more work done by us.
Unfortunately LT doesn't have many tools to check CH credibility. Saying that, I didn't take part in this contest only because of Ivan warning. We can also try to asses every contest by ourselves and rise red flags if we have suppositions.
