I'm no lawyer, but given the company has investors, I'm pretty sure the SEC can still come after them if they're misleading their investors. Sending out a press release saying your company is making $100B would be very much like what Madoff did. They can still come after you.
Also, think revenue numbers are a bit harder to fudge, so doing a sanity check off of those based on how many people they have, I think it's in the right ballpark.
