I know what a real scam looks like; I used to investigate and prosecute them. However, it would seem that, amidst all the noise, there is no real evidence - supposition perhaps, but no evidence; which is what a court of law would require.
Further, your claims of "evidence" seems to not be as readily obvious to the regulators. And, if you wish to argue they would not bother with such a small company, you have no clue - they would love a slam dunk. But, since it seems there is no slam dunk, if you have evidence, please contact the SEC.
If not, you might want to re-check the laws related to libel.
As for MLM, he might be of the highest integrity...but, what evidence do you have that he can run a company? Again, that tricky word - Evidence!
