I know it's a long document but if you keep reading, it tells you why Reg S exists.
Regulation S is available only for “offers and sales of securities outside the United States” made in good faith and not as a means of circumventing the registration provisions of the Securities Act. The availability of the issuer (Rule 903) and the resale (Rule 904) safe harbors is contingent on two general conditions:
1. the offer or sale must be made in an offshore transaction; and
2. no “directed selling efforts” may be made by the issuer, a distributor, any of their respective affiliates, or any person acting on their behalf.
...and actually the crooks would have to be in the US since Reg S applies to a US company selling shares to entities OUTSIDE of the US.
