Point made about the possibility of a complaint never having been sent to the SEC.
As for your assumption that they "FOUND NOTHING to be concerned about", it's impossible to know for sure, as you very well know.
Perhaps a complaint had been made which is what finally drew their attention to those 6 years of no financials...a violation on which they did act.
With no further investor losses now possible (due to the revocation), it might be fair to surmise that an intense (& expensive) investigation of foreign principles may not be a high priority for the SEC. But again, we both know that they work painfully slow and will never comment on even the existence of an investigation.
It's only been 9 months since FFGO was revoked...plenty of time, years even, for charges to still be made, although personally, I don't ever see that happening. Lumb was just too careful and knows exactly how to legally work within the system.
