Anyway, this is going out of subject, so let's focus on the initial question.
The initial question has already been answered. We can't do a thing, at least for now. The only way is to trust the one who will send you the coins or/and from where. Since the coins are coming from a KYC-regulated exchange, then are "clear". However, if someone wants "virgin" coins will have to start mining. With all these terms of pure crap, we can't avoid their story and their strategy of controlling everyone.
